[deleted] That's because NFC payments won't work since GrapheneOS is not certified by Google. There was a small window of time at one point in which Google changed something that made NFC payments possible, but the change was reverted. The OS does not pass the checks Google requires to be considered a certified Android OS because it does things like adding the network and sensors permissions (for greater privacy and security, of course). If Google wanted (or any other app which uses Play Integrity API), it could support GrapheneOS by following this guide: https://grapheneos.org/articles/attestation-compatibility-guide.
