Apple Music stuck on "Library Synchronization" after importing tracks from Spotify

I signed up for a trial period on Apple music, in the music application all the tracks are turned on, but in the library there is a "library synchronization" plate hanging in one position for 10 hours, I used the Tunemymusic service to transfer tracks from Spotify to Apple music

What could be the problem?
