I am using the latest windows store build, as of writing and I am not seeing live tiles on two PCs (one installed the Plex client for the first time yesterday, the other one was showing old data until I disabled the live tile and turned it on and now it shows nothing)
I have enabled logging, but all it seems to show in regards to the live tile is:
2016-11-11 22:40:28:4290 [2] DEBUG - [LiveTileBackgroundTask] - Live Tile is enabled
I can't see it doing anything with it afterwards, I can of course provide more logs, but I was curious if others have been seeing the same?
