no it should work out of the box. Check if magisk is installed correctly. does it show magisk version in manager?For my k30Pro the apps can't get access to superuser. Is there an option I should use?
I have reinstall the rom and the magisk.zip.The reinstall can not fix my problem.
i tried the vw financial services app and if i check it in magisk hide the app will no longer show the security warning when launching it.
did you do any other modifications? does safety net passes? did you hide magisk manager and activate magisk hide in settings? is your device certified in google play? (some general troubleshooting questions)
