Gapps should be included in your flash queue when you did the update. Freeing your storage and flashing the gapps in twrp should fix it
I try different roms and with all roms have that problem.
I had the same problem on this one and PixysOS before that.
I used NikGApps instead of FlameGapps, but otherwise it was the same for me. Couldn't access the Play Store at all.
The thing that appears to have helped me with Google Play certification was installing Magisk and setting it to Hide.
Although I also flashed this PixelXL Coral ZIP before.
But if I remember correctly this didn't fix my problem.
1. All valuable files backed up on PC, Migrate archive created last week also copied to PC.
Mine says it's Pixel 5I've noticed that my Google drive storage isn't decreasing even after uploading many gigabytes of videos and photos from my crDroid 7.4 Poco X3 NFC phone. Upon checking google.com/devices it showed that my X3 is identified as Google Pixel 4a.
This means that videos and photos Do not count towards my Google drive quota. Nice!
People on crDroid 7.8, can you please check what Google sees your X3 as? Thanks.
