I appreciate you joining the thread, @InaraSolutions. 

Although there's no specific time frame when the issue about recurring transactions not disappearing on the Reminder list after being used will be resolved, I can provide updates on the investigation's status. 

As of posting, the status of the investigation is closed. However, I recognize that there are still users who are still experiencing the same issue. With this, I'd still encourage contacting our Support Team to add you to the list of affected users. This way, the case will be reopened and you'll be notified through email once the issue is resolved. Here's how you can reach out to them:

1. In your QuickBooks Online company, go to Help (?).

2. Select either of these tabs:

• Assistant tab and type Talk to a human.
• Search tab and click on Contact us to connect with a support expert.

3. Choose how you want to reach us (phone or chat).

For Simple Start, Essentials, and Plus, support is available Monday to Friday from 6 AM PT to 6 PM PT and Saturday 6 AM to 3 PM PT. For Advanced, support is available any time and any day.

Should you need help with any other QuickBooks Online (QBO) concerns, let me add this resource: Self-help articles.
