Hey Wojciech TrockiI just give it a try and the app does not crash anymore.

On the web version if you hint the back button the website is going to redirect you again to Keycloak Auth page.

On the Mobile version if you hint the back button you will be able to navigate on the app, but not be able to see/add tasks. The tasks page can be visited but it does not work. Maybe we should block the access to that page if you are not logged. Wdyt?
