Thanks for the continuous effort!
- I took my phone with the unofficial LOS20, applied the version in the OP, rebooted => Various Google Apps crashed
- Reapplied MindTheGapps-13.0.0-arm64-20221025_100653 => No more crashes, but the Play Store app says it’s offline
- Reapplied Magisk, unmasked it, remasked it, Zygisk off, Zygisk on, with reboots => no luck
- Cleared data & cache for Play store, reboot => no luck
Any clue to make Play Store online ?
