The announcement mentions Plex will discontinue support for pre-WebOS LG models (your LG 43LJ5500 uses webOS 3.5).
For Vizio, Plex will no longer support older models running their “Presto” platform… for some reason it’s a bit tricky to find adequate technical details from that manufacturer, so I cannot verify if those 2 models are going to be impacted or not (D24-D1, D32f-E1)
Do you have any manuals that show what “platform” those tv-sets are running on?
