Premium Features Stopped Working

Just after a couple of weeks into my Premium subscription, I am unable to use the premium features this subscription should enable. For instance, during the free trial I was perfectly capable of using the background/ object detector in no time! I was then able to amend the background selection, etc... Now this feature does not work anymore! It will tell me to wait for the photo to be downloaded, but it apparently never happens and even for the easiest photos to detect the background, the app cannot do this. Such a waste of time, considering I am never able to use this important feature! I mainly bought photoshop for this.
