@Tears Burn
I am sorry to be back with a problem again and I have tried troubleshooting myself, with no luck.
I updated my Marble from HyperOS 2.0.5.0 to 2.0.6.0.
I reinstalled Magisk alpha and all my banking apps are working, apart from AIB (again).
SPIC returns as "No Integrity" and key attestation is showing bootloader locked, yet despite that, GPay, Revolut, N26 and broker apps are all working. But AIB is detecting root.
My next planned step is to uninstall Magisk Alpha and modules then reboot and reinstall Alpha and modules in the sequence as per your original post (Which worked perfectly previously).
I just want to ask before I do that, is there anything else you think I may be missing it making an error about?
Really appreciate your previous help with this and any advice will be appreciated.
