This packs can be installed on A11+, the other ones not. Is it possible to remove invalid packs from the panel?
But they DO work if you install them on devices running older versions of Android. So you can install them on (for example) an android 9 device then copy the installed files to your newer device and they (usually) work fine
Are you on 3.75? The newest release should have fixed this
I don’t have old devices with android 9. Unfortunately …
I have 3.74b , waiting for stable
