live tv not working for all users in plex home

hi guys!
personally i find live tv a great feature, but everyone except me (in my plex home) can’'t watch it. the video starts for a few seconds, but stops after 10-30s playback. then it starts again, stops, starts, … not usable. it’s also very easy to reproduce. i just need to change the user on the same device (firetv stick) and it stops working. back to my user and it’s working great. as long as everyone uses my account everyone can watch without an issues (differnet channels as well as the same).
did anyone experience the same behaviour or how can this be fixed?

i use a hd homerun tuner (4 tuners) with a PMS running on debian (cpu: intel xeon)

i’ll be happy about every hint to get this fixed :blush:

can someone please comment on this? or let me know which logs you require?
