Tips for a smoother interactive presentation experience on iPad

Some presentations in Mobile Locker are interactive HTML experiences (often called IVAs, or interactive visual aids). They can include animations, carousels, overlays, and many images. Those presentations use more of your iPad’s memory than a simple PDF or static slide deck.

On a busy work day, with email, browsers, CRM apps, and other tools also open, the iPad may occasionally free up memory by clearing the presentation screen. That can look like a blank page, a partial screen, or content that needs a moment to return after you switch apps or wake the device.

This article explains practical habits that reduce how often that happens and what to do if it does. It applies to any team using interactive HTML presentations in the Mobile Locker iOS app on iPad.

Before each call

1. Start from the Mobile Locker main screen.
   Open the interactive presentation only for this call, not one that has been sitting open since earlier in the day.

2. Close heavy apps if you have been using them.
   From the app switcher, swipe away apps that use a lot of memory in the background, especially:

   • Browsers such as Safari or Chrome (especially with many tabs open)
   • CRM apps such as Salesforce, Veeva, or similar tools your team uses for calls and accounts

   You can open those apps again after the presentation when you need them.

3. Handle email and CRM tasks first when you can.
   Check mail and finish CRM updates before you open a large interactive presentation so you are less likely to jump back and forth during the call.

4. Avoid splitting the screen.
   Present full screen in Mobile Locker. Side-by-side apps (Split View) make it harder for the iPad to keep a large presentation running smoothly.

5. Give the iPad a little breathing room.
   If storage is nearly full, free up space when you can. A very full or very warm iPad can feel sluggish.

During your call

1. Stay in Mobile Locker while you present when possible.
   Switching to email or another app and coming back is when blank or recovering screens show up most often.

2. Try to keep the screen on while the presentation is open.
   If the iPad locks or the display turns off mid-call (auto-lock, cover closed, or the side button), Mobile Locker goes into the background. When you wake the iPad, the presentation may take a moment to return, or look blank until it reloads. That is similar to switching apps.

   • Before a long presentation, consider a longer Auto-Lock time in iPad Settings (or keep the iPad plugged in / on a stand so it is less likely to sleep).
   • If the screen does go off, wake it, unlock if needed, and wait a few seconds for the content to restore. If it stays blank, use the recovery steps below.

3. If you must leave Mobile Locker mid-presentation (another app or a locked screen), give the app a few seconds when you return.

When you finish (and between calls)

Treat each call as a fresh start:

1. Reveal the Mobile Locker toolbar if you do not see it.
   Interactive presentations often hide the app’s navigation bar so the content can fill the screen. There may be no visible Exit button inside the presentation itself.

   Tap the top-left corner of the screen (a Mobile Locker “hotspot”). That brings up the Mobile Locker presentation toolbar.

2. On the toolbar, tap Back or Close (often shown as an X).
   Which control you see depends on where you are in the navigation stack (for example, whether you opened this presentation from the main library or from another presentation).

3. Return to the Mobile Locker main screen (keep tapping Back/Close until you are out of the presentation stack).

4. For your next call, open the presentation again from the main screen only when you need it, then leave it again when that call ends.

A large presentation left open (even with the screen off, or under another app) keeps using memory. Opening it once in the morning and “living” in it all day makes blank or sluggish screens more likely later. Leaving the presentation after each use frees that memory so every call starts clean.

Habit to remember:

Main screen → open presentation for this call → present → tap top-left to show toolbar → Back or X until main screen → next call.

If something looks wrong

Try these steps in order:

1. Leave the presentation (tap the top-left corner to show the toolbar, then Back or X) and open it again from your library or main screen.
2. If it is still blank or stuck, force close Mobile Locker only (from the app switcher, swipe it away), open Mobile Locker again, and reopen the presentation.
3. If it still fails, restart your iPad, open Mobile Locker (and only the apps you truly need), then open the presentation again.

You do not need to force-close every other app unless problems continue after step 2.

Quick checklist

Before each call

• On the Mobile Locker main screen (presentation not left open from earlier)
• Closed Safari / Chrome and CRM apps (Salesforce, Veeva, and so on) from the app switcher
• Not using Split View with another app
• Ready to stay in Mobile Locker while presenting (and keep the screen on when you can)

After every call

• Tapped the top-left corner if needed to show the toolbar, then Back or X until the Mobile Locker main screen
• Did not leave the presentation open for the next call (turning the screen off alone is not enough)

Why this matters

Interactive HTML presentations run inside a web view on your iPad. Large image-heavy experiences use more memory than lighter content. Other apps, especially browsers and CRM apps such as Salesforce or Veeva, and locking the screen also affect how much free memory the iPad has.

Newer iPads often handle large presentations more easily. Older devices, or iPads with many apps open in the background, are more sensitive. Following the habits above helps on every device.

If your organization builds or receives custom HTML packages from an agency, developers can also reduce memory use in the content itself. See the related articles on this page for developer guidance on image size and memory limits for HTML IVAs.

When you report an issue to support, please include:

• Name of the presentation
• Date and time when the issue occurred (as exact as you can; include your time zone if you know it)
• Screenshot(s) if you can capture what you saw (blank screen, partial content, error message, and so on). Screenshots help us investigate much faster
• Whether the screen went blank, froze, or looked wrong after switching apps or after the screen locked
• iPad model and iPadOS version if you know them
