Checklist
1. Confirm the connection is subscribed and not paused.
2. Confirm bank consent is still valid; reconnect if the bank requires renewal.
3. Confirm the account is mapped to a YNAB destination.
4. Run a manual sync; if still empty, the bank may not have published new transactions yet.
5. Review duplicate and overlap behaviour at how BudgetSyncer prevents duplicates so you do not mistake skipped overlaps for a failed sync. Frequency FAQ: how often BudgetSyncer syncs.
