Hello jon-nuckels,

This happens if you connect parent a credit card account and its sub-accounts.

You can't connect the parent account and sub accounts at the same time. This triggers the error you get. You'll only need to connect the account where your transactions are downloaded. If all transactions go the parent account, just connect the parent account. If they are downloaded to the individual sub-accounts, you can connect all sub-accounts.

Here's an article for additional reference: About Bank or Credit Card Sub-account Setup.

If you have additional questions, please go back to this thread.
