Got an odd issue with 4k firestick if any one can share any light on this or experienced it themselfs, my iptv got its own branded app and on the 4k stick in living room when i go on one certain channel it will play for 10 seconds or so before video freezes then when i go out to change channel it crashes the app and i go back to the main menu ob the fieestick itself, doesnt do it on same app on the old 2nd gen stick i got runnig in the bedroom, any ideas or a fix for this thanks in advance
