Genuine question: is no banking app access really a showstopper, if that is the only thing missing? My bank app does not work on CalyxOS, but it has turned out to be no problem at all since I always use my laptop for serious banking tasks anyway. Are browser based bank apps starting to be phased out forcing people to use mobile apps? Is it just a preference?

For me, the lack of certain phone features has been the showstopper. I still need my phone to be a phone. So postmarketOS is not going to work on my phone. I recently learned that Ubuntu Touch supposedly has full support for my device, including phone stuff, and I want to test it out, but I am trying to get a cheap second-hand version of the device to test.
