Lagging problem in my iPad pro

​Hi @Cinar Cobanoglu 

Hope you're doing well and thanks for taking the time to post about this.  

As described, you have started experiencing this issue recently, after upgrading to iPadOS 26.5.2, there might be a chance that the new iOS update is causing performance dips across the apps. iPadOS 26 introduced a new multi-app stacking feature that runs background processes even when you're not actively using it, which can cause noticeable lag during scrolling.

Please try the steps below and see if that works:

1. Open the Settings app on your iPad Pro.
2. Tap Multitasking & Gestures.
3. Select Full Screen Apps.
4. You should feel a performance improvement almost immediately.

If that doesn't fully resolve things, here are a few more steps worth trying:

5. Make sure Acrobat Reader is fully up to date, open the App Store, tap your profile icon in the top-right, and scroll to see if an update is available.
6. Force-close Acrobat and relaunch it: swipe up from the bottom of the screen, swipe the Acrobat card away, then reopen the app.
7. Clear the app's cache: go to Settings app > General > iPhone Storage > Scroll down and select Acrobat > Tap Offload App > reboot the device and reinstall the app from the App Store.
Note: Offloading an app removes the app to free up storage space while keeping your documents and data intact.

9. Test with a simple, lightweight PDF (a plain text document rather than a graphics-heavy file) to check whether the lag is file-specific or affects everything.

Could you let us know the following? It'll help us narrow things down further:
- Which iPad Pro model are you on (M1, M2, M4 chip etc.)?
- What version of Acrobat Reader is installed (tap the three dots > Help > Version)?
- Does the lag happen on all PDFs or specific files?

Let us know how it goes.
