IMDb notifications stopped

  I've been using IMDb for years, and one of my favorite features on the Android app is that I get notifications alerting me to when movie titles from my watch list become available to stream, and when movies from my watch list will expire soon on my streaming channels. All this ended over a month ago, and I no longer get any kind of notifications from the IMDb app. I have triple checked all my settings on the IMDb app and on my android device settings, and everything looks normal, all the right boxes are checked. What happened?
