Termux isn't even able to call the su at all, but file managers have different levels of root. MX can do anything, but Root Explorer can do about 90% of normal, but all others are locked down. On A11. OnePlus 8 Pro. I was only adding to the FM issue, not trying to hijack the thread.

Same issue here on a OnePlus 9 pro running the last android 13 OOS release. File managers and terminal apps can't receive root permissions on any magisk version past 26.3. Root permission granted to apps before upgrading to 27.0 continues to function as expected but any new su permission granted with 27.0 or later silently fails.

I found the solution. Disable zygisk assist and Shamiko, reboot, run the terminal app it will ask for root, grant it then you can re-enable the two mods, reboot, and the terminal app will still work with root afterwards. Also file managers.

So the thing is, the partitions also can't be edited. I disabled dm-verity.

Expected.
