Broken notifications on IMDb app

I have my IMDb app set to notify me when a movie on my watch list becomes available to stream. Or when it is coming to theaters. Or when a new episode of a TV series will drop. I have not gotten a single one of these notifications in at least a month.

Then lately I started getting them but for movies I already watched. They were once on my watch list, then I rated them and removed them from my watch list. And yet I get notifications that they are available for streaming. I confirmed that they were no longer on my watch list. It has happened multiple times. It's not a one-off.

Please fix.
