GrapheneOS alien2003 Not a regression caused by GmsCompatConfig version 124. It may be caused by Google Play services or Google Wallet updates. It's possible they don't allow adding cards on a non-Google-certified OS anymore.
alien2003 I'm sorry for nagging you. No regression, fixed by allowing Location access to Google Play Services. After adding card, I revoked it again, works perfectly.
