Since day 1 Apple Music has been frustrating when traveling in my local area where there is poor mobile phone coverage. It has improved since the early days when downloaded offline songs would disappear after loosing mobile signal - now they are still there. What's fustrating now is that after a few minutes of listening to downloaded songs in a low signal area Apple Music flags that you need to sign in to Itunes again, showing a box to rewrite my password. When driviing it's impossible (and dangerous) to have to type in the password again. Considering Spotify, especially with the new family tariff.
