I already read this problem here: Covers of TV series missing
Sounds like it’s fixed since 6.4.1, but for me it is not.
On my ATV 4K, randomly after entering the app ( not everytime I re-enter the app ), some covers are missing, and until I go into the folder the art won’t reload. It’s a bit annoying, and curiously I never had this problem before ( started like 1 month ago ).
The TV shows concerned don’t have any activity ( I’m not watching them or adding new episodes ).
Thank you !
