My frost bank transactions are missing for 6 months. I spoke with a QB rep early last week and they said it was a known problem. So….what is and when is my fix?

You have to import the data manually for the time being or use a 3rd party tool to do so. Unless you know the Investigation case number, they won't share any updates until it's fixed

Hello there, @rush-danika.

Yes, we're aware of this issue. This has been raised to the banking engineers to understand why this unexpected behavior is happening. For now, our engineers are still working on resolving this and we're not given any time frame when it will be sorted out.
 

As Fiat Lux - ASIA's suggestion, you can manually upload the bank transactions using the CSV file to continue bringing them to QuickBooks.

Download transactions from your bank by logging in to your bank's website. Then, follow the given instructions on how to download transactions and save the file on your desktop or anywhere you can easily find it.

 Once done, upload them to your book by following these steps:

1. Sign to your QBO account and select Transactions on the left panel.
2. Click the Link account drop-down arrow.
3. Select Upload from file. Then, click the file you've saved on your computer.

You can use these articles as additional reference in fixing bank upload errors, categorizing transactions after importing them, and the reconciliation workflow in QBO:
 

• Learn what to do if you have issues when you manually upload transactions.
• Keep bank transactions organized.
