This thread is about Plex Media Server versions 1.40.2.8273 and 1.40.2.8312 causing Plex Dash to fail to load any item history. It was fixed in Plex Media Server 1.40.2.8351.
The problem you’re describing isn’t related to the above issue. As far as I can tell the item details pages are working everywhere except in a few specific cases (TV items, but only when opened from either History or Now Playing. Search, Charts etc work just fine).
The cause is related to the rewrite/redesign of the details screens. I’ll have a fix in the next Dash release.
I’ll mark this thread as solved again as the issue is unrelated. Please open a new thread if you’d like to discuss further.
Edit: the fix is out now.
