It’s Google Play Integrity checking now, and as someone who has been using LinageOS on unrooted phones for a while, I’ve never had these issues. Not to say people out there aren’t having them, but it’s not as bleak as people seem to believe it is

Maybe a week ago they borked the integrity of custom ROMs. GPay/Wallet doesn’t work anymore with Magisk shenanigans. Happened to every ROM I checked.
