Hi there, just after upgrading the LG TV (65OLEDC9PLA) firmware to the latest version (04.70.05) I'm having a Problem with buffering: Now the Plex apps (like "Plex" or "Xplay") is buffering too much (just 1 minute ago before the upgrade, the apps never buffered at all). It's very annoying and it's not happening to "Emby" app.
So to test these issues you can install "plex server" in any local network computer and just serve the Dolby Core Universe demo that you can download here. At some point of the video, the app will start buffering (It didn't happen before the firmware upgrade).
