Hello All,
Those who are root lovers and developers who likes to use root phreak devices comes accross various issue. Same thing happened to me when I rooted my Oneplus 11r phone and installed magisk. Surprisingly when any app requires root acces example Root Explorer, I was not able to get root access even granting permission to it. Here is the solution to the issue.
Issue: Unble to get root acces even giving root permissions
Cause: Seems like bug in magisk or so (not confirmed)
Fix:
1. Open the app asking for root like AdAway
2. Deny the root permission(most important step)
3. Force close the app
4. Open Magisk manager
5. Go to SuperUser
6. Toggle the switch to enable root acces
7. Open the app and check root acces
Comment if you have any questions.
