Hi, Hamid. It's definitely a hurdle when constant disconnects interrupt your workflow with busy professionals. As your clients have encountered, this occurs when your financial institution has additional security measures, such as security questions or one-time passcodes for authentication or verification.
Since you've already reached out to RBC and they mentioned that QuickBooks is aware of the issue, I recommend contacting our QuickBooks Online Live Support team for an update. They can check this behavior further and help ensure a consistent connection to your clients' bank feeds.
- Go to the Help icon and select the Contact Us button.
- Briefly describe your issue or type it in the box, then Continue.
- Choose either Chat or Callback for help.
In the meantime, you can manually upload your transactions in QuickBooks via CSV to keep your records up to date.
Please let me know if there's anything else I can help you with, and I will respond promptly.
