I've installed gos yesterday and so far everything is working even my banking app, but today when I needed to authenticate my online payment in said banking app it didn't work and the app didn't even showed me option to do it. I don't have another device with me at the moment so I can't test if it's in the app or not. do you think it's maybe because of the os ?

    ejbejos maybe try enabling compatibility mode in settings --> apps --> (your app)
