Here are the most common reasons issues happen:

1) Cross-border and merchant risk rules Ad platforms process payments through different entities depending on your region. If your business is in one country but the ad account is billed by an entity in another, some cards or issuers flag it as higher risk.

4) Mismatched billing info or unsupported payment flows Small mismatches (business name, address format) can be
