I like this superuser app  and I've sort of got it working with Android Pay  with Xposed & Magik Mask; Root Checker confirms root and SafetyNet Helper passes. however... Superuser doesn't show any prompts  toasts or logs. This could be something to do with the way I've installed - when I check my phone's overview with SD Maid  the Su binary shows as Chainfire 2.72 I can't find anything obvious (to me) in the XDA thread  as I've flashed the supplied superuser.zip and there is nothing in the app itself about updating binaries Edit - I've got it to work thanks to a full rom system update which would have removed Chainfire's SU binary  flashing Magisk-v2.zip seemed to sort everything out  too bad my bank isn't on Android Pay & this doesn't help get my banking app (Barclays) to work yet
