settings are not saved

[hype11]

Hello,
I installed Tusky with version 24.1 on my Android 13 (iodéOS) phone.
At start I can select mastodon-instance und login into my account with password.
But after using another app for a while and start tusky another time, all settings are gone and the first screen appears to select mastodon instance und login with password.
What am I doing wrong or is this the intended functionality?
