Hello @leal5264,

Thank you for taking the time to post in the Community. Let me share some updates about the missing option in QuickBooks.

The investigation is still open, and our team has not declared a specific time-frame for the complete fix. Rest assured, the engineers are doing their best to fix and prevent this from happening again.

In the meantime, I recommend applying credit notes to invoices manually. Here's how:

1. Select + New.
2. Select Receive payment or Receive invoice payment.
3. In the Customer dropdown, select the customer.
4. In the Outstanding Transactions section, select the open invoice you want to apply the credit note to.
5. In the Credits section, select the credit notes you want to apply.
6. For the open invoice in the Payment column, enter how much of the credit you want to apply.
7. Leave the Payment method, Reference no, Deposit to, and Amount received fields blank.
8. Fill out the rest of the form, including the Payment date.
9. Make sure the total is correct after applying the credit note.
10. When you're done, select Save and close.

Since there's no update yet, it may be the reason you haven't receive notifications via email. You can also follow up by contacting our QuickBooks Support Team.

If you still have the case number, that would help streamline the process. Your case number has the previous agent's notes according to what happened to your issue. This way, you won't be repeating yourself.

For more information, as well as how to apply a delayed credit, I recommend the following article: Create and apply credit notes or delayed credits in QuickBooks Online.

Thank you for your patience while our engineers are working on the resolution of this problem. I'm just a post away if you have any other questions.
