I have a fairphone 6 with the curve app installed on /e/OS 3.7.2 (same issue on 3.7.1).
More often then not when I try and pay using my phone, via tapping, with the curve app installed the payment terminal rejects the payment saying it sees multiple cards. I only have one card configured in the app but this persists. Curve have not been able to provide a solution.
Anyone else seen this?
