Tidal problems

Are you sure you are accessing the high rez version? Tidal sometimes offers multiple resolutions for the same album.
Beyond that, did you try resetting the app?
I got the update and it works fine, though I did need to delete the previous version manually. It might be conflicting with the new version.

Tidal is the exclusive streaming music that offers lossless music. 

If you'd like to download music from tidal, you just need to use an lossless audio capture. 

Hope this tips help you out.
