I can confirm that the Postfinance app doesn't work on graphene. I left some feedback and they said they're working on it so maybe there is hope. But as such I need to keep an old iphone around for banking apps.

Also being an American in Switzerland trying to do banking is eye opening. Local banks mostly tell you to pound sand when they find out you're American. Regardless of this or that administration, the US is really totalitarian when it comes to finance and taxes.
