i installed BANK app .. i opened , it seems to work ! i didn't enter with credentials only cause i'm allowed to use it just over one smartphone and i still use the old one !ok, thanks for that, found it and its a .zip file that i then went into magisk itself to install, however the banking app still wont play-ball unfortunately - from reseaching, some say that some of these banking apps cld be also be scanning for other 'root' app, that if you have installed then it is deemed that the phone or device has been rooted, for example TWRP. Titanium Backup, Root Explorer etc etc.
Ah well, it not really a matter of great importance to have to use the banking app, i can still use their banking website
...and yeah, there is now a v1.20 of the safetynet fix app.
i do remember though if somethng was wrong i couldn't even open it !
