Has there been a recent change in qbo to disallow connecting parent and sub-accounts? I had them connected already, one parent and three subs. To reconcile, I reconciled the parent and made a JE to balance the other accounts. All accounts are on one statement. 

The problem arose when I tried to add a fourth sub, and I get the error message that I can't because it's a sub-account of an account that is already connected. But the other subs are still connected. And the transactions from the new sub aren't importing with the parent at all. I've disconnect and reconnected, using different browsers and incognito windows. Can you tell me why I can have three subs connected but I can't add the fourth? There is no difference in how they are set up.
