We hear you, @whiteviper.

I appreciate you for reaching out to our live support to fix your bank connectivity and ask why some accounts aren't showing on your page. Let me share information and direct you to the best help.

Currently, a new investigation (INV-95713) about missing accounts in the connection window in Elan Financial Services has been created. I recommend contacting our QBO Live support again to acquire updates about the investigation and temporarily ask for a workaround. If a fix is available, an email will be sent to you.

Here's how: 

1. Click the (?) Help icon above.
2. From the Search, tap Contact Us below.
3. Type in a short description of your banking concern. Then, Continue.
4. Select how would you want to connect with us. Chat or Callback.

The available support for chats is Monday to Friday, 6:00 AM to 6:00 PM PT, and for callbacks, the same days of the week from 6:00 AM to 5:55 PM PT.

Once fixed, you might want to use bank rules to categorize your bank transactions automatically, check this article: Set up bank rules to categorize online banking transactions in QuickBooks Online.

Thank you for raising your concern here. Please reply to this post if you have additional banking account-related questions. We'll be willing to lend a hand. Keep safe always.
