I have a parent credit card with two subaccounts. I can only see parent card transactions. The subaccount transactions are not syncing.

Hi there, larimoremhps.

You only need to account one account if both the parent and sub-account has online banking. If the transactions download to one account, connect only the parent. If the transactions download to the individual accounts, connect the subaccounts and not the parent. Here's an article for more details: About Bank Or Credit Card Subaccount Setup

If you can't see the sub-account's transactions in the parent account, a possible browser issue might be preventing QuickBooks from downloading them from your bank. I'll provide some steps that can resolve common browser issues when working in QuickBooks Online. 

First, use an incognito/private browsing session or a different browser. Follow these keyboard shortcuts to open an incognito session: 

• Ctrl + Shift + N  for Google Chrome
• Ctrl + Shift + P  for Firefox
• Control + Option +P if you're using Safari
• Ctrl + Shift + P for Microsoft Edge

You can also use any of these browsers if you have them installed in your computer. Once done, check if you can already see new transactions.

If everything looks good, proceed to deleting cache and other saved data files within your browser. Here's an article as a guide: Clear Cache And Cookies To Fix Issues When Using QuickBooks Online.
