Love Service- Hate One Thing About App

I love this service. It has every song Im looking for. It has-hands down-the best radio and playlist selections of any other app because of their purchasing of Songza a couple of years back. And the ability to save music to the cloud as well as stream music is very convenient and nice.

MY ONE ISSUE: the app continuously tells me that it "Cant play this song because device storage is full". I have a 16GB iPhone 6 Plus. Sure its a little old and the smallest storage space. I still have over 150MB of storage space-plus the whole reason I stream music is to NOT have to save it to my phone. Why would it be unable to play over my network connection if my storage was full? There should be no data being saved to my phone. Even if it is caching it-it should just stop and stream the music entirely from the internet. I dont get it.

Would be a 5 star app if that bug would be squashed to death!
