Why some of my playlists on Apple Music are disappearing?

I would like to know why some of my playlist on Apple Music are disappearing!! Last month it disappeared my classical music playlist and 1 week ago it disappeared another one and I would like to get them back, it’s a lot of work to create a playlist and watching them disappear without even doing anything it just sucks!

I did not make anything for them to disappear, and I have tried a lot of things to get them back and at the end there’s nothing I can do…

Please Apple give me back my playlists.
