Spontaneous SQLite db rollback

Cheeger 1 Reputation point

My Xamarin App stores data in several SQLite databases.
Data is added to them during the day, I can reload applications many times, sometimes changes persist even after device reboot.
But at some point all new changes disappear and LastWriteTime of all databases becomes 19.01.1970 19:41:44.
Because of what it might be?

I testing on android 9, journal_mode of all databases is set to delete, they are stored in the files folder of my app, app is now only checking LastWriteTime dbs.
