WhatsApp age restriction after being hacked

My WhatsApp, Facebook, Instagram, Messenger and email were hacked. I recovered everything except WhatsApp.

WhatsApp now says “This account violates WhatsApp’s age requirement.” It tells me to go to Facebook, but my Facebook works normally and my age is already confirmed. The Facebook button just opens Facebook and does nothing.

I have reinstalled WhatsApp, cleared the cache, updated it, tried registering again and waited 24 hours. There is no “Request a review” option.

WhatsApp support is AI automated replies.

Has anyone had this happen? How can I get my WhatsApp account back?
