SuperSu does not grant root after app update


SuperSU, by default, removes root permission to apps having been updated! So you may notice after an app update that root features are no longer functioning as expected.


This is caused by an option in SuperSU called "Re-authentication", enabled by default which requires manually granting again root to any udpated apps having been granted root previously. Sadly this option has been turned on by default and may cause any root apps to malfunction after an update.
