What are the steps that we need to take to reproduce your problem?
When you start playing a serie or movie on your television it loads (a little longer than before the update) and starts. After ~30 secs it stops and start buffering, before starting 2 secs to start buffering again. I have 3 other Samsung TV's running other OS (not Tizen) with the newest version of Plex App, with no issues with Plex. I even tried to reset the entire TV. No problem before the update (streamed a 4K movie with no lag, no loading time.. No I can't watch an episode of The Flash (20 min)) This update came a few days ago.
I tried switching from 5Ghz (which has full strength and can stream 4K from Netflix with no issues) to 2.4Ghz and even took a LAN-cable to ensuring myself and Samsung that this was not the issue.
Does it happen with every file of this media type or just some?
Not file specific, happens randomly after short amount of time, even tried to change the settings (quality eg.) with no luck at all. Reached out to Samsung Support which logged into my TV to conclude 'The TV seems fine, so we can't do anything - It is most likely something with Plex to do, you'll have to wait for them to release an new version'.
