When I try to look at my collected shows I get a gateway timed out error (504 specifically). “users/{username}/collection/shows” gives the 504 error while “users/{username}/collection/movies” works as expected. I’ve tried both through the website and through the API. I get the same error.
You have 275k items in your collection. That is an extremely high number and causing the page to timeout. Do you really own 275,000 movies and episodes?
