This issue is also present with GrapheneOS sandboxed compatibility layer using stock play services.

Does the app require something that isn't supported by MicroG or GrapheneOS?

as a workaround i've been using a separate qr code app, obsqr. it opens scanned codes in the service vic app and allows check in.

I also found that turning on cloud messaging and google safetynet (temporarily) allow the addition of a vaccine certificate. unsure if this would also fix the qr scanning issue.

unsure if this would also fix the qr scanning issue.

I did a test on a device that didn't pass safetynet but had completely normal Google Play Services and QR scanning worked fine. GCM might be the issue, but I doubt it.
