My Question or Issue

One of my playlists ("Fine Electronic") is empty but I did not empty it myself (at least not intentionally). Unfo it's not deleted, just empty, so I can not recover it. It happened yesterday or the day before yesterday, not sure. It's empty in both Android app and Desktop Linux app. We also switched from premium to family some days ago, but I think it should not be related.
