The user in Xiaomi EU forum reported a bootloop after granted root permissions to Root Explorer to uninstall Notes app. He tried to report it as a bug, but Igor Eisberg replied to him:
"Not a bug, really. Dynamic partitions are meant to be read-only and once modified, they become corrupted. This has nothing to do with our ROM"
The problem is when you grant permissions and then reboot, some users suggest to revoke root authorization in Magisk Manager before reboot to avoid boot loop.
