I no long receive notification banners for new episodes on my iPhone.

Starting about a month ago I stopped receiving pop up banner notifications on the current shows I watched. Instead for a couple weeks I received the random notification from Apple TV instead, but even that has stopped. Ironically last week and today I did receive a notification for new episodes of Widow’s Bay through IMDB, which is an Apple TV show. However I still do not receive notifications for any other shows.

I checked my in app settings, where I turned everything off then back on, and logging out of my account and then back in did not help either. Since then I’ve signed up to be notified via e-mail, but that misses a show on occasion too, like ‘American Dad!’. I could not find anyone with the same issue, so I don’t know if this is a well known issue. What can I do?
