Came after 3 week suspension …Started playing game game sound works connecting to team voice chat nothing happens shows i connected but when i talk my picture icon doesn’t appear i see other players icons shows that they talking in voice chat but i can’t hear them and can’t speak with them…I spent all this day to find out i even uninstalled game than app and installed fresh and nothing still no changes…I talked with 4 support game masters and they all said silly kid staff-connect and disconnect headphones go to sound settings disable and enable bla bla bla…So basically i tried other games and everything is fine except this game so i guess this is some kind of system glitch that my voice is muted from server side and i can’t normally play competitive because i can’t communicate …Any ideas??? Sorted out!!! I found similar Post from some good gamer who explained how to sort out problem…Unfortunately it wasn’t a game masters which one i contacted today 5 times and none of them wasn’t even close to help me !!! Thank you !!!
