During 30 % of my matches, I am only able to hear my teammates for like 3 minutes before their mic icons are gone. This happens when I play with friends on the fireteam as well, and it seems to happen randomly.
I sent a thing to 343 on the support page, but no response yet. However I want to know if anyone else seems to be facing this issue, because it is very annoying to face this issue during a Ranked match.
I have a photo example on reddit if anyone wants to see what happens when the bug happens.
