My voice chat is randomly gone and i cant hear anybody even thought im age verified and have had voice chat forever. When i visit https://voice.roblox.com/v1/settings it also confirms that i have voice chat enabled and i am not banned, as well as in my settings where i have voice chat enabled
Im having the exact same issue as you, I think its due to the fact that roblox is disabling VC for some users whilest rolling over to age based chat. I wish they were more transperant about that though because for all we know we may never get vc back.
It will give you useful information weather its a bug or the rollover thing.
Basically if its the roll over thing the “denialReason” will be 3. (Also keep in mind this is just from my own research so I could be wrong but I fairly confident that I am correct)
