Here is what you do, go onto the spotify app on your chromebook and click on the 3 dots on the right hand corner, then click on app info. Once you do that, click allow protected content. and then refresh the app. Now it should be working! If youre on the web player on chrome browser then just press on the lock symbol on the left hand side of the url on top, then allow protected content right there. Refresh. Now it should be working for you too!
Unfortunately, I am having the same problem, yet I DO have the app on the chromebook. For me, it's not working for the app, the web extension, NOR the incognito mode. I have tried everything I could think of doing, yet nothing has worked. Thank you for your help, though, Elena!
I've been having the same problem! Unfortunately, I can't download it, because my computer isn't hooked up to a Google App store. I guess I'll have to use YouTube for the time being until this problem gets figured out.
