Update of PMS messed up Live TV

The newest update has caused a new problem. I was able to watch the same TV channel on multiple TV’s at the same time before the last PMS update. In other words lets say I was watching ESPN in my Living room whiles also wanting to watch the same ESPN on my deck at the same time caused NO issues. Noe when I try the second TV ask me to watch Live or Start Watching from the beginning. Either choice loads the channel but in then freezes the picture then Plex crashes. Can you please fix this as I use multiple TV’s on the same channel very often for sporting events and other program. BTW I am using HDHomerun Tuner for cable and had no issues before this last update. This is using Firesticks GEN. 2.
