Qobuz vs. Tidal

I guess I have to be more careful when deleting. Perhaps I will use the Qobuz app on my phone. 

Many thanks as well to the individual who was kind enough to share his playlists!

I have an Aurender A 15.

I decided to delete some tracks on two different playlists. I simply swiped them and pressed delete. Sounds simple enough. I ended up deleting over 70% of the playlist and have no idea why that happened. I've done it before with any issues.

I've tried to get help from Qoboz and can't get a response. Many users of Qobuz have indicated their CS leaves a lot to be desired. 

How does one learn to use Qobuz?

I am using version 4.

Many thanks to all for your thoughtful comments and suggestions.
