I
I am now using a @Displax USNF mod build and also I think I lost device integrity when I went to add a card in Google Pay/Google Wallet maybe when it went to contacting your bank or when I clicked on set up payment card.Please confirm that you are actually using a @Displax USNF mod build... It's still not clear although it's usually needed for deviceIntegrity w/ A11+...
Next, consider and say what changes you made between having and loosing deviceIntegrity... Nb. Even when nothing is wrong with a setup any longer, clearing Google Play Services data is sometimes (often?) needed to restore deviceIntegrity etc... Some users have even needed to disable USNF module (official or forked), reboot, enable and boot again to fix...
Seems you did tick Google Play Services (gms) processes... See discussion above... Perhaps screenshot w/ MEETS_DEVICE_INTEGRITY missing was taken before rebooting (ie gms in denylist not yet removed and still breaking the PI fix)?... Could be an added module etc too... PW
