1. I encountered this issue on PC, gamepass
2. I was playing WITH FRIENDS
3. I was playing as all heros
4. doesn't happen when solo, obviously

Steps:
Start game, open up game to friends.

Result:
Voice chat, even when selected to "OFF" (not push to talk nor always on), is on (comes across to other players). Fixed by going into menu and selecting the other options and then selecting "off" and saving. However, when the mission is completed and returned to either the main menu (due to party disconnect) or, if lucky, party returns to base camp the setting is reverted back to the on position (again, the setting is in the "off" position)

Expected Result:
Voice chat in the "OFF" position should be off.
