We are aware of the issues, and have already fixed the problem however it’s caused an issue when switching audio streams in Live TV as such it’s been disabled in the beta.
It’s involved a major rewrite of how our playback stack works for HLS and isn’t a 20 line fix.
If you aren’t switching audio streams whilst playing Live TV, there is a build available here that you can can use: Fire Stick stops playing live tv every few minutes, exits to guide. ([FFmpeg] [ERROR] [tls @ 0x81b7e740] Error in the pull function.) - #233 by sixones
If you find the above build works for you, I would suggest you disable auto updates until we provide a new build that fixes the audio stream switching, once that is resolved we will be rolling the changes out ASAP.
