Is this a new bug? Cannot recall if this was the case before but the artwork has swapped and it’s a real bug bear of mine!
Also any idea when/if there will be a webos beta
I think there’s been a request to show season posters in hubs to better represent where an episode belongs (e.g. in continue watching, recently aired or episode playlists/collections). Plex has started to apply that in the regular/classic client and seems to make an effort to do this consistently in the new experience.
According to the announcement thread, other big screen platforms should follow „soon“ (now that the app is available on tvOS). However, there’s no ETA.
Thanks for the quick reply - hopefully Plex give users the choice between the 2, I would definitely prefer show posters rather than season posters with more words strewn across and can be harder to find a clean version of due to less metadata matches - this would create a lot of work for some people!!
