Hmm I rather have spotify exhaust all possible issues with thier backed ,before do the clean install etc run around that really won't get you anywhere in 99% of cases 🙂
Also it would be good for spotify to investigate before I reset ,if the problem goes away then it would remain a mystery as why . If I get in contact with a spotify rep and they tell me to reset i would do so , me thinks they should at least try to fix it first . I don't like the idea that clean install should be the first port of call in trouble shooting , that idea is more about making me go away than finding the issue ? Now I know that iOS devices are a bit silly it's not easy to find and copy files or logs or anything .
If the app requires regular resets to work properly it's very clear that's that is also a bug .
