Fair point. I haven't actually tested the banking mobile webapp but I did test it from a regular PC and oh boy, it was like a 1999 web application.

Not just because of the look and feel but everything was just odd and in the wrong places compared to the store app. I should probably try this from a mobile browser but the last time I used Firefox in Postmarket OS it behaved like a desktop browser (in fact I think I read somewhere that it is indeed a regular Firefox resized to be used in PostmarketOS) so I'm assuming that the experience is going to be really bad.
