Sometimes, a green circle in the Banking section means there's a bit of a delay in downloading the data, goconnie1.
We can try a few browser troubleshooting steps to get rid of that spinning circle. First is to refresh your QBO by restarting the browser. Then, reopen QBO and go back to the Banking section to see if it's working again.
If the same thing happens, you can proceed to the second step which is to open your account using a private window. If you can access the Banking section there, then the behavior has something to do with the browser's cache. You can clear it out by following the steps in this article.
Please let me know if the steps I gave fixed it. I'll be right here if you need more help.
