On Xperia 10, SFOS 5.0, microG 0.3.15 and MobilePay 10.9.0 works just fine.
I logged in using my existing bank-id app (transferring), not registering using my passport. That’s the only time it asks for NFC, right?
It could be that registering a new certificate is the only time NFC is needed, I am unsure. I have never tried transferring, since I wanted a backup in case something went wrong. Maybe transferring is what I should go for. I will look into this and make a try.
All possible persons should send feedback regarding this to Mobilepay. In current climate I can’t understand why they lock things down
