Invalid Can't convert to system app

[Bangle88]

Hi...after the last update (9.1.3 - MiMax2), I can't convert any user app into system app, both manually and by many app like LuckyPatcher or Link2SD.
I have downgraded to 8.12.27 and it works.
I have root permissions with Magisk.

We don't provide root-related support. Our ROMs don't come pre-rooted, so it's up to you to solve.
