Most payment failures come from the card issuer. The most common fixes: - **Update your card** on the Billing page — expired cards are the #1 cause - **Contact your bank** — many banks block "unknown international merchants" by default; a quick call unblocks us - **Try a different card** — temporarily use an alternate card to restore access We retry failed payments 3 times over 7 days. After that, access is paused until billing is fixed. Your data is safe — nothing is deleted, access is just read-only.
