Bank-dependent by design
Open banking does not guarantee that every credit card product appears as a syncable account. Some banks expose card accounts alongside current accounts; others only return checking and savings. BudgetSyncer shows the accounts your bank returns after consent — we cannot invent a card feed the bank does not provide.
After you authorize, check the mapping screen. If a credit card is listed, map it to a YNAB credit card account (not a checking account) so balances and payment flows stay correct in YNAB.
