SkynetPrime Factory reset on my pixel tablet complete.
Problem does not go away. After factory reset and going threw the setup, your presented with the normal first home screen (no second home screen)
Using Obtainium (only way i install my apps), once first app is installed a second home screen is made and the installed app goes there.
Playing around i turned off in home settings Add app icons to home screen then reinstalled another app, as expected the app does not go to any home screen. Once turning on Add app icons to home screen and then installing a few more apps, my original problem occurs.. Apps do not go to any home screen. However once forcing the launcher app to Stop, all the apps that should of gone to home screen instantly create a second home screen again and go there.
Not going to bother factory resetting my p7a now as kinda pointless and only working around that makes sense now is just to turn off Add app icons to home screen and just move the newly installed apps from the launcher. Note PWAs will still create a second home screen and install there.
I officially give up now with this issue lol
