I have the same problem. I just dont see the quality in Spotify regarding many things. This doesn't work. I wonder when they will start expanding the App into many different things. What will be the percentage of things that will 100% work. I guess we are all their "premium" QA Team.
I've got the same problem, also behind a proxy (cntlm, if it would matter). Also some images inside e.g Artist view will not show up (e.g whatever image there should be under Popular section before the index number). Does CEF ignore spotify proxy settings or something?
After all this months making this question shows that there is no QA Team at spotify , Sorry starting by complaining. So this wont work with or without proxy. I have tried both ways. You can contact your internal support team or Open an internal ticket. They will confirm that this is not working. They can figure it out very quickly and simulate proxy usage. Maybe you cna even try it yourself and join this long list of unhappy people .
