Vanish mode not available?

I created two new profiles 15datys ago and i dont have vanish mode option on one of them.

I tried everything, reinstalling app, connecting with old facebook profile, adding it to account center, changing from private to public and from personal to creatir and to business,

i tried finding update messaging option and there is non.

Does anyone has any trick idea how to get this option? The other profile has it. I also tried deactivating and activating but nothing happened. Help please
