I updated LG app to Emby Theater 1.0.24
My emby server is Synology NAS, just updated to 188.8.131.52 (but issue existed before this update).
There is no way to go "home". In the upper left corner, there is a "back arrow" when you're down from the home page (when you move the mouse). But this is "back", not "home".
Previous releases included a home option under the profile icon. That profile icon now goes to "settings", with no home option. There is a Home Screen entry, but that's home page settings, not go to home.
I see on the web interface (Chrome) there is a Home icon in the upper left corner. The LG app doesn't have a Home icon, only the back arrow.
Attached are some cam shots (my wife and I share the profile...). Let me know if you need more detail.
