I’m guessing if you don’t have any subscription from Soundcloud you can’t use it in engine dj. At least that’s the case in any other dj software I’ve used. But I was expecting an error message when I log in with my free Soundcloud account . “No subscription found” or something. Instead it’s loading forever giving the User the feeling something isn’t working. Maybe this could be added in a future update.
(don’t know if this is the right place for something like this. But I thought some feedback could help)
