google pay

OK. This is the case, I have tries to make a payment with google pay the entire weekend with my new note 20 ultra, but with no luck, I contacted Samsung support without any help, they blame google pay and maybe the app needed a update. I took contact with google pay support and we tried a lot of things to make it work, but they again cant see anything wrong with the setup on my phone and it should work. But today I tried one last thing, I took out the sim card and tried to pay for somthing, and it worked, WTF! I tried one more time with putting it back in but set the phone on flight mode, this did not work, So the conclusion is the google pay app works when I take out the simcard, anybody know how to fix this issue?

I am experiencing the same issue in Finland. Did u come up with a solution? Thanks in advance.
