This issue has been verified Visual Studio Code 1.96.3 (9.0.30 & 9.0.22) about 5 times. Can not repro this issue on Android-arm emulator and Samsung SM-S9010(Galaxy S22).
I want to confirm with you: Is your issue reproducible stably? Is it only repro on arm-android devices? Could you try it on an android emulator to see if it can be reproduced? Looking forward to your reply!

Hello,

I want to confirm with you: Is your issue reproducible stably?

On my Samsung SM-A137F phone, I reproduce both issues every time like the video.
The application is used by thousands users, and some other phones have the issue like on Samsung SM-A325F (Galaxy A32)

About the application crash, verified it using Visual Studio 17.13.0 Preview 2.1 (9.0.30 & 9.0.22). Can repro on Android API 21 emulator, but not repro on API-35 emulator.

[Eskissimo]

Unfortunatly, despite many tries, I can't create an emulator to reproduce the problem of items disappearing. I'm on Windows so I couldn't test the configurations with ARM processors.

If it can help the issue can be reproduce on Samsung A336B (Galaxy A33)

@Eskissimo If you are going to use a BindableLayout with a large number of elements, I recommend switching to using CollectionView. Remember, the Layout does not use virtualization or recycling cells etc.

[Eskissimo]

@jsuarezruiz I understand for the crash, but the main issue is elements becomes hidden.

I know CollectionView is better, but I can't use it because i have an user interface which already have a parent scrollview (the real UI is more complex than the sample project).

The issue is solved with the version 9.0.40 SR4.

Thanks!
