Bad….I see the situation bad.
Banking apps under AppSupport are a lottery. There is a thread dedicated to it –> Banking apps on Sailfish OS
I tried MS Authenticator in the past and never worked, at least for me.
I have tested neither CIEID nor proton apps.
As far as i known, Google Wallet can not be used with AppSupport as it depends on Google Services and is a Google native app. Unfortunately, there is no App in SFOS with the same functions.
Look, I have been using SFOS since the beginning. Even earlier, with the N9. I have always had a secondary Android for such situations…not optimal, but it is what it is…
