Play Integrity Fix 17.9 unable to attest in LineageOS for MicroG 21

[tgm-git]

I have recently installed LineageOS for MicroG v21 on my FairPhone 4 (FP4).

Furthermore, I have have installed Magisk stable (v27000) and flashed PIF 17.9. I have magisk systemless host installed also, but no other modules. When ever I try to run an attestation using Play Integrity Checker or SPIC I get an error related to binding to the Play Store.

The error code is -9: Integrity API error (-9). I have found a screenshot of someone else having the exact same error. Not sure if this is a problem with MicroG, PIF, or something else entirely.

I am running the stable version of MicroG, which might be part of the issue
