Dictionary popup slow

In Netflix, when I hover over/click on words, it takes about 15 seconds for the popup dictionary’s contents to load. After that, words load quicker for a short while (a minute or two), but then the issue returns. Sometimes, a warning “Error saving item” pops up even though I haven’t attempted to save anything. I’m studying Chinese Simplified subtitles, and the issue doesn’t seem tied to a specific video or series.

It has been like this for at least a week (the issue could’ve cropped up last week, but I didn’t use LR to study last week so I wouldn’t know).

BTW Language Reactor has been an incredibly useful tool in my language studies. Big thanks to the LR team for all their hard work!
