I got my first fraud flag on a new Amex yesterday, ~$100 bill payment via PayPal. Called them up and they verfied me by one of my other Amex cards, unblocked no problem. But now I can't add it back to PayPal, I get a message saying the (Amex) app can't verify me...it still works with Amazon, but looks like I'm going to have to wait for the physical card.
This was my fourth and only two months since last, also first which wasn't an instant approval (they wanted to confirm it was me who'd applied, but after that all well). Oh well, 6 months to spend $3k is ok (Hilton Surpass, the Hilton SUBs are particularly attractive atm imo, and I'm still in PUJ for Bonvoy cards!).
