My Question or Issue

I'd like to import all mp3 files at the local of my phone to Spotify .

I've already imported about 1,400 files and I can listen to these songs on Spotify.

This time, I added about 30 files to my phone.

However, importing these files never ends although I was waiting more than 12 hours.

(To my memory, it took only 10 minutes for importing 1,400 mp3 files)

I tried below actions, but nothing worked well.

* Delete the cache of application

* Restart application

* Restart device

* Remove and then reinstall application

* Delete all mp3 files in my phone and then copy them to my phone again

Does someone help me?

Best regards
