probleme with Apple music, please help me!

Bought yesterday Apple music after a 3 months trial.

In the 3 months everyrhing was ok.

So, yesterday I bought Apple music, and I have alot of problemse.

Behind songs there is a "+" to add the song , when I click on it , it ask me to sinc it to the music or replace it.

So , I click on sync , but after that , iam not able to download a song, there isn't a "+" button behind ANY song any more.

Apple music library auto. turns off all the time . (Apple music is bought om the same iTunes and app store account , and logged in)

I tried to log off and in , and reset the phone.

Apple music library still auto. turns off.

And when it is off, all buttons "+" and "cloud" button for downloading and adding songs are visible but, not after I go to settings, music , and turn it on again.

Hope some one can help me.

Kind regards

Alexander Heldens
