Xbox one in-game chat not working?

I have been playing sea of theives for a while now and I’ve seen it go through many changes but a big problem I have been facing, and especially recently is xbox one in game chat not working.
Once and a while me and my friends can speak in game and the next day it fails to work one bit. We have tried everything from unplugging to resetting. My friends on PCs mics work in xbox party and game so it’s not mics?
