When using, it plays well for about 30 sec, no lag then it goes back to the first channel of the list and continuously does that every 30 seconds. I dont think it is connection issues since it is cabled. What im suspecting is that i logged in mobile and tv though never played them both simultaneously. I did not have this issue on mobile which was wifi.
Im using mibox 4k , iptv smarters apk and it was a TRIAL
Try Tivimate. Works fine in my mibox
