Hi there, MRC2.
What's your bank provider? Did you encounter any error message? Aside from updating your software, let's make sure you're currently using the supported version of Internet Explorer.
Then, try switching the Bank Feeds mode from Classic to Register mode and vice versa to see the accounts in the Bank Feeds page.
If the same thing happens, you can check out this link for more troubleshooting steps option: Banking and Bank Feeds. Then, go to If you run into a problem (Bank Feeds) section.
Feel free to reply to this post if you have more questions. I'm here to help.
