Im using a OnePlus phone with Android 12, currently on game version 6.3.9 but this is going on since over a week ago (maybe the unity 22 revert?not sure).
If i hold the tab button i can normally put an app in splitscreen mode and have another app on the bottom half, (eg youtube + idle slayer).
If i try it with Idle Slayer now i get a system pop up "App doesnt support splitscreen"
It worked before and only the default Clock/Alarm app has the same restriction.
aighty, much love
