Thanks for laying out the details of your concern, @dcv.
The syncing of bank transactions in QuickBooks Online (QBO) will depend on your bank. Thus, I suggest reaching out to your financial institution first to see if there are any ongoing problems with syncing your transactions to QBO.
However, if you have verified with your bank that there are no issues on their end, I recommend reaching out to our Technical Support Team. They have the tools to check your account securely and perform a screen-sharing session to investigate this behavior further.
