This show Billions: Season 5 (2020) — The Movie Database (TMDB) , has been updated more than 72 hours ago, but plex Season 5 of Billions (2016) | Plex is where to watch your movies and TV has not picked up the changes. Thought it took up to 48 hours to cache. Is it stuck?
Thanks 
In my experience its approximately 48 hours but can take up to a week depending on what metadata type your waiting to get to plex.
I usually start questioning things if after a week they don’t arrive.
that’s too much. a plex employee had informed mr that it usually takes up to 48 hours
There’s a bug when refreshing the data for this specific show, it’s being investigated
thanks for the response
@Invisible_Plex_User this issue has been fixed, thanks for the report
