The situation changes every couple of months, can't figure out if they unbroke it already.
In the end this whole "buyer protection with percentage fee" is about the banks thinking: "We don't want to be a dumb digital sock for people's money. We have to provide value to them". But I want my bank to be a dumb digital sock to put my money in, nothing more. I'm really getting fat-up with all these MBA-types's thinking their company "needs to have a relation with me and add value". I mean I get emails from my utilities trying to get to know me. Seriously? I don't give a wooden nickle about my drinking water supplier. I just want to pay them and use their services and other than that I want to think about them as little as possible.

Wero is a mess.
The app however is only secure as long as your system isn't rooted. To make sure it isn't rooted you need to ask somebody who signed the system image if the integrity still holds.
I heard interesting ideas about phones, such as all phones having secure enclave and hsm which the app is totally using, so you can't just lift both the encrypted secret and it's kek from the same filesystem
