Oneplus 9 Pro / NFC Payments: Mobiles Zahlen / Sparkasse

Dear all,

I read earlier that a few users were able to add their Sparkasse debitcard to NFC, but I’m struggling, I even went to advanced privacy und unchecked the tracker ocurrences.

In NFC I see the app activated - no not sure what else I can do. I read other users they were able to make it work. All apps come from the app lounge. Thanks in advance.
