I agree with WedgeStratos. In my case 2 of 3 banking apps work with Aurora store.
→ Perhaps a list of supported banking-apps could help in future (something like VoLTE-list)
My personal work-around for the next time:
I only have two important apps, that actually don’t work with Sailfish. I need them once a month or once a year for authentication. In this case, I use a usual Android-tablet of our family. And hopefully it will be possible to do all things on Sailfish in future
