It must be very frustrating! I've not much experience of the problem and I use virtual cards which I change all the time, but a significant number of people do have problems. Check out the forum for this, maybe you can find a solution there, though not everyone has the same reason. I had an issue at the beginning which turned out to be my fault. I had switched off authorization for international payments and then forgot I did it. Sometimes the problem can be with Meta and sometimes with settings in your payment or financial services provider that causes this. Maybe double check it, or if you have a, spouse or partner try their card. I actually used my wife's before figuring out what my problem was. Good luck, I hope you get it fixed. βοΈ βοΈ π€ π€ P.S. Definitely check around the forums if you've tried what I suggested already.
