HERE IS ONE SOLUTION TO CUT IT OFF:

@Tutanota The easiest way is to also delete everything with Canta, yes even GMS
@Kurosetii @Tutanota some phone might stuck into bootloop
@GOKUSHRM @Tutanota I haven't had any bootloop issues, at least not on POCO device
@Kurosetii @Tutanota have you deleted Google play service app?. Try that
@Kurosetii @Tutanota let us know what happened.
@GOKUSHRM @Tutanota I will, but in case of bootloop I can try netguard so it blocks Google Play Services from using the internet so it doesn't run in the background and send data
@Kurosetii @Tutanota I'm already using it and cut all the internet option for GPS... I also disabled GPS but thn some apps won't work properly.
