Good evening, I bought all 3 specializations on 03/24/2021: Technician, gunner and firewall. I can activate the technician and firewall but I cannot activate that of the gunner .. the "activate" button is not available. If I go to the white house and go where there are specializations, it tells me that I have all 3 new specializations but it does not make me active that of the machine gunner .. even check the lock. What can I do?
