I have updated the app since that I get stuck in loading black screen with emby logo
Tried reinstall it without success
I don't know if the update is related to compatibility to newer webos version I am still on a mid 2023 webos version because the TV is jailbreak
I can reproduce this issue - not everytime, and I know the issue - it is a bit of an obscure one.
Try this when it's stuck:
Press Home to display the app ribbon
Navigate up to the 'Emby' app title on the top left Hand side
Select the 'x' close button that appears - this will close the app.
Relaunch the app
