buffering issues since latest update - Plex

For buffering issues since latest update and the Plex Ever since the latest update that talked about fixing buffering issues.. I have started to experience buffering issues. The files worked and played fine previously. Now the files play at slower speed.. where 1 would be normal speed. It plays at like 0.6 speed for 4-5 seconds and then starts buffering for 10-15 seconds and then plays another 4-5 seconds at a slower speed without any sound.
Do I need to do something within Plex to fix the files for this newest update that was released? Analyzing the files or something somehow?
Is anyone else experiencing these issues since the latest update?
Any help would be appreciated.
