No warning if credentials cannot be loaded
We still from time to time see a bug with the Flatpak version of the app, that the credentials don't load and the user has to restart the app.
The issue is, that the user gets no information about that issue - they simple don't see that the credentials are not loaded and will just wonder why changes don't sync to other devices (well, because they don't if the app does not have credentials).
There shall be some kind of feedback to the user that accounts are missing secrets and hence the sync cannot work yet.
