Tidal - 4 on the floor

You're not supposed to lose anything when logging out. As long as your subscription is up to date, all information is still in the app.
I had to log out once during some troubleshooting to reconnect to my network.

I'm certainly not going to complain about the Qobuz price reduction. Qobuz's library is growing every day and so are subscriptions. Meanwhile, Tidal's customer base has not expanded and allegedly Jay Z is in talks with Square.

Tidal has some good features, the most useful being offline use, but I prefer Qobuz for my musical taste. And the consistantly good SQ is a good reason for audiophiles to subscribe.

"It's not an issue." 
Well, that's really lame. If you ever have a technical problem like I did, the instructions were to log out, then log back in to reconnect.
