Cache Update Loading Optimization

Currently, UX of tracking the watched videos on the web (trakt.tv) is not as good as on iOS app. I usually binge watch TV shows and check off the watched episodes manually. On the web, I can’t do that fast as I need to wait for cache update for a few seconds from three to ten seconds. Sometimes, if the timing is not right, the caching went wrong and the UI is not updated correctly like no check mark even though the data is updated which needs the total site refresh with clean cache and site data. Other times, it creates duplicate tracking and I need to keep track of the watched history regularly to remove duplicate entries. Unlike web, on iOS, I can simply just update one after another continuously without having to wait. Can you please update it so that the UX on web is similar to iOS app?
