Hi there, Chrostopher. Do you see any specific error message when your bank account goes unlinked? That detail will help me provide the exact solution for your situation.
It's also a good idea to check your bank's website for any ongoing maintenance or security updates that might be causing this issue.
If everything appears to be normal on the bank's side, try logging into QuickBooks Online (QBO) using an incognito or private browsing window when relinking your bank account. Sometimes, browser cache or stored data can interfere with the bank connection, and using a private window helps rule that out.
If the issue continues, I recommend contacting our Live Support Expert team for further assistance with this.
In the meantime, you can upload your bank transactions manually using a CSV file to keep your books updated: Manually upload transactions into QuickBooks Online.
