Thanks for returning to this thread, @DJW17. I can provide additional information about manually uploading bank transactions as an alternative to updating in QuickBooks Online (QBO).

I can see the importance of when the connection resumes, and since there's no specific timeframe for resolving the issue, let's manually upload transactions for the moment.

Once the connection resumes, there would be a possibility of duplicate transactions. However, we can have an option to review those downloaded transactions and exclude duplicates:

1. Sign in to your QBO account.
2. Go to the Transactions tab and select Bank Transactions.
3. Select the For Review tab.
4. Click on the checkbox of the transaction you want to exclude.
5. Select Exclude.

I've attached screenshots for reference:

The excluded transaction will now go to the Excluded tab of the banking page. If you've excluded the wrong transaction, you can click on Undo.

For more information about excluding bank transactions in QBO, please refer to this article: Exclude a bank transaction you downloaded into QBO.

Also, I'd recommend contacting our Support Team so you'll be added to the specific INV related to your scenario and be prioritized in receiving email updates about the progress.

For future reference, you can utilize this article to learn how to create bank rules to automatically categorize bank transactions and put them to the right accounts: Set up bank rules in QBO.

Let me know if you require further assistance importing or updating bank transactions. I'd be glad to assist.
