strcat I'll try it again using the two devices, however I showed the exact error messages above. (see https://discuss.grapheneos.org/d/1191-auditor-failed-integrity-check/6)
The initial error is shown in the "Error Pixel 3a XL auditee" image.
I cleared the auditee and auditor pairings and the local test results were reproducible. I also waited for the first test and I noticed the auditee QR code reading from the Pixel 3a XL takes a long time but I always let it finish.
The date on the Pixel 3a XL is correct since I made the initial test on October 3rd, the other tests were made on October 7th.
The remote attestations were successful for both devices. For the 3a XL and the 5 the first result was "Successfully performed basic initial verification and pairing." and the subsequent ones were "Successfully performed strong paired verification and identity confirmation.".
