Thank you for raising your concern here on the Community page. Let's figure out the possible reasons why your bank stopped bringing transactions to QuickBooks. Then, ensure to keep bank records correct and up to date.
To get started, I would appreciate if share can share the specific bank you're using so I can determine and check if there is an ongoing issue with the bank. In the meantime, let's retrieve those transactions by doing a manual update to refresh the connection between your bank and QuickBooks Online.
Thank you for posting here in QuickBooks Community. I'll provide information about transactions that are not downloaded.
