I have 83 movies in my watchlist and since I’m not a member the limit is 100. But I can’t add new movies to the watchlist. It is showing that they are being added but they are actually not showing up in the watchlist.The added to watchlist icon is showing that its added but its actually not adding up.
Might be a cache issue.
You can try resetting it: Settings > Advanced > Reset Browser Data
Have you TV series in your Watchlist as well, or is it only movies?
Watchlist includes both movies and shows combined in the summation. You have 83 movies but probably bc of your shows it is over 100.
I see 93 items on your watchlist now, so is it working correctly to add now?
