It happened again: After MMA crash all manual playlists disppeared

I am not quite sure what exactly forced the crash, but here is what I remember...

- This morning I was casting to google home speaker
- playback stopped after playlist end, not sure if casting connection was still alive.
- I left my home and wifi connection got lost
- i tried to open MMA to play music to my bluetooth headphones
-> MMA was stuck at the home or splash screen, I do not remember exactly
- I switched to my podcast app and forgot about MMA
- tonight I wanted to play music with MMA and sadly remembered what happened this morning as I realized that all playlists are gone.

That's sad. Your database was probably corrupted and the recovery process failed too.
That's why you lost your synced data.
We plan to implement a backup option for the library database so that it can be restored from an old backup.
It may be useful in cases like this.

When synchronizing a large amount of data, sometimes the upload takes too long and the sync fails due to a timeout.
This should be optimized in MM5 and MM 2024.
Luckily, re-syncing as you did also solves the problem.

I just noticed that the database seems to be broken too. All song ratings are missing.

When doing a sync with MMW4 MMA showed "matching new files" for all mp3s. After that finished, MMA showed "synchronisation starting" for hours and I cancelled the sync.
At that point song ratings for most songs were recovered.

I had to restart sync a few times as it got cancelled again and again.
But finally MMA synced all files and playlists again.

Today MMA crashed and almost all playlists were deleted. I cannot say what triggered the crash. I was listening to some songs via Bluetooth. Playback ended and I pressed play at the headset some times to restart playback of the now playing list. As playback did not start again I opened MMA and it was hanging.
Then I restarted MMA and it was rescanning all media. This process finished but almost all playlists are still gone.
