Hello,
I saw sometimes in AppCenter these 2 errors:

Error 1:

Expected behavior

No errors

Steps to reproduce the behavior

I have not reproduced the problem on my devices

Configuration

Plugin Version: 2.2.1

I saw in devices with:

• Device: Redmi Note 9

• OS Version: Android 12

• Device: Galaxy A31

• OS Version: Android 12

• Device: moto g04s

• OS Version: Android 14

and other Xiaomi phones

I have only 1 suggestion: Add logs before await MediaGallery.PickAsync(...) and before await mediaFile.PlatformOpenReadAsync().

You should check if the activity instances are different from Microsoft.Maui.ApplicationModel.Platform.CurrentActivity
