Revolut works perfectly for me.

What kind of issues did you have? I think it does require google play services (which can be installed easily).

I have used GOS on a pixel 6 for the past two years with no issues. The phone finally died on me last weekend, so I'm in the market for a new pixel which will be getting GOS right away.

Can you please clarify the Revolut part? Just to understand, you are saying that you are able to perform NFC payments via the Revolut app which you installed on your Graphene OS through the official Play Store?
