Hi there, @jenlfrost-hotmai.
We have received several reports regarding this, and our Product Engineers are now working to fix it as quickly as possible. While they do, I recommend reaching out to our Customer Care Team, so you'll be added to the list affected users. To reach them, click the Assistant button at the top-right corner and type in Talk to human. Ensure to review their support hours so, you'll know when agents are available.
In the meantime, as another option, you can manually upload your bank transactions using a CSV file. Check out this article for the steps and details: Manually import transactions into QuickBooks Self-Employed.
Once done getting your transactions in, you'll want to match or categorise them.
If you need any additional assistance while managing your bank transactions, you can leave a comment below. I'll be sure to get back to you.
