i know this one, is very simple to fix, all u need to do is verify the card they ll cut a 1$ verification payment that will be refunded, and it ll come with a code they ll ask u to put to verify, the worst case is that they say sometimes the card has insufficient funds eventhough it has, and the solution for this case is simple, u go to one of ur pages an u submit an new engagement post for 1.33$ budget, u wait few hours and u come back, it worked 80% of times with me, u see ad acc back active and that campaign of 1$ started to spend and then u can use ur account super normal
