i currently have the spinning circle of death also but my workaround is different to what is suggested was going to post the issue here but noticed this thread so added to it. i am using a Samsung 6 series smart TV not got the model number at the mo.
press sources on my remote
instead of going to HDMI 1 2 etc i just scroll along to emby symbol (which is not the app)
takes a bit of what i will call extra common sense to get to where you want as its very basic and just has folder structures and files nothing else only reason i tried this as the app was showing in the whats new section of the apps page so figured app must of been updated but dunno when as apparently Samsung appears to not think it relevant to provide this but it was working last night
the app has all the information it needs and DOES see the next episode but folder structure does not show and eps and clicking next episode causes circle of death after loading up the ep info as there is nothing below the description i can stop circle of death but page is not responsive at all to arrow keys and have to back out
i assume this is because the app is not seeing/showing them in the directory but does know its there due to the next episode feature?
p.s. uninstalling the app and reinstalling the app was tried @ 14:00 ish gmt along with many library scans
actually noticed that the tv info is on the dashboard so re edited again to paste it
Samsung SmartTV (UE49K6300)
Emby Theater 1.0.48
