Can't delete episode review

 storyteller-ish:

I can click delete, but when it asks me if I'm sure, an error pops up when I click "OK." It just says "Something went wrong."

I have the same problem, wanted to delete the rating of all episodes in one drama and I just can't.

 Also, when I want to delete all the timestamp of my watchlist, clicking on the "delete" button it doesn't work. I will appreciate if someone can fix it, thank you.
