Just a few helpful things to check, as many things can Trigger SN,Can't get my device to pass attestation now. Installed the latest universal fix 2.1.1. There are currently no Android 12 fingerprints for props config. It's failing both basicIntegrity and ctsProfile, does say eval type is basic. Magisk is hidden. gPay and Play Services are 'hidden', cache and storage were cleared. Phone was rebooted. Funnily enough the banking apps work, but gPay does not.
And it may be possible that one of the Magisk betas need to be used to get it passing, but tbh I haven't read enough about SN/A12 just quite yet, but this thread, if you haven't seen it yet, has a bunch of information on the state of Magisk, and those having issues passing SN with A12.
