When People Are In My IOS Party, my mic stops working

I have updated the controller and it still doesn’t work, it still doesn’t output my mic even though I can hear the mic. However I have noticed when I join a party for half a second my xbox outputs my mic then it just stops. Is that of any help?

Unfortunately, none of these answers fixed this for me. Update though: looks like I can hear everything the other people in my Fortnite party is saying, they just can’t hear me. The weirder thing is, when I squad up with randos, the mic works just fine.
I can hear them and they can hear me. Again, same thing when I’m in an Xbox Live party. The only thing that doesnt work is my mic when I’m in a regular Fortnite party (not in an Xbox Live party).

What I also find interesting is that when I turn the controller off, and remain in the party, the light next to my name will activate when I speak into the mic while the controller is off.

I have also had success using the mic when I run an app - such as TV, but then the mic will stop working upon loading a game - such as Grand Theft Auto V.

I am convinced this is a software issue, especially because people above have purchased new headsets without successfully resolving the problem.

I've been experiencing this. Usually occurs when I go out of range with my controller and come back into range it says my mic can't cant be detected. The same occurs when I unplug the mic and plug them back in. I can usually get the mic working again by
unplugging the mic, hitting the nexus button and going up to the party so I can see the orange warning symbol over my icon. When I can see this, I plug the mic back into the controller and the symbol disappears and I can hear people in the party again after
a few seconds.

my mic doesn't work in game chat i try to talk to other players with mics and they can't hear me even though it shows my mic emitting noise next to my name. It works fine when im in parties though.
