VIPPS mobile payment app stopped working (Norway)

The norwegian VIPPS mobile payment app has stopped working. After the app was updated to version 8.23 it wouldn’t work on my FP4 with e/os v3.01.

I uninstalled it and reinstalled it. The app uses the norwegian BankID system for authentication which seems to work fine but I am never returned to the VIPPS app. BankID works fine otherwise.

I contacted VIPPS support and was told that only Chrome or Safari was supported. Chrome won’t install on e/os and I don’t want it either.

Any ideas anyone?

Maybe you can have a look at this link where the same issue is discussed for the Danish version of Vipps called MobilePay
