I checked the thread
https://forum.sailfishos.org/t/pizza-jolla-e-mandolino-the-italy-related-android-apps-thread
and I also gave a contribution for Fineco.
The main issue I can see with the app I mentioned is the missing use of biometrics for login.
Every app requires you to enter the password for every login. It’s quite impossible to remember dozens of passwords for every day usage.
