Iptv buffers but not on phone ?

[Aristotle]

Tivimate on one firestick and providers app on other firestick and phone .

You probably have altered the buffer size in Tivimate but what do you have it set to?
Also do you have multi room for both FS’s or just watch one at a time?

What sticks are they? Basic, 4k etc

i was pulling my hair out over this....but in my case changing from hls to mpeg instantly fixed it.....only for that provider i had the issue with.
