Has anyone struggled to reauthenticate their banking app after signing out quickbooks for multiple months?

Hi, glenheadwoodservices. There are a few reasons your bank account cannot connect to QuickBooks Online, including browser cache issues, pop-up blockers, or maintenance on your bank’s website.
 

Have you tried disabling your browser’s pop-up blocker? This allows the pop-up window to appear and connect your bank to QuickBooks Online. We also suggest logging in to your QuickBooks Online account in an incognito window to see if that resolves the issue.
 

If the problem continues, our QuickBooks Online Live Support Team can conduct a more in-depth review. You can find their hours and contact information here: How to get help with QuickBooks.

Alternatively, you can import your bank transactions using a CSV file from your bank. These guides explain how to format and upload your file:
 

• Prepare your CSV file for bank upload to QuickBooks
• Manually upload transactions into QuickBooks Online

Once imported, you can categorise your transactions in QuickBooks Online as usual.
