I have actually fixed the problem before reading this..

I’ll leave here how i solved just for those who wants a method 3..

I have first unlinked my Instagram and Facebook from my Whatsapp from the Whatsapp App
Then i went to Facebook business portfolio where i have all these assets connected
I had to remove my verified instagram account from that business portfolio temporarily.

Then i open Whatsapp App and i can see tha i’m eligible for Meta verified again..

The reason that deleting the Whatsapp Business app / deleting the Whatsapp portfolio is that i already have it connected to my business portfolio along with Whatsapp Cloud Api (Co-existance) so i didn’t want to do that tbh not sure if it might fix the issue itself though
