Helping you is our top priority, @Julian Mendoza.
Currently, sending automatic reminders to your customer even if the feature is already turned off is reported as an investigation. Rest assured, our product engineers prioritize this concern and are working tirelessly to resolve as soon as possible.
With this, I'd recommend contacting our Customer Care team since they can add you to the list of affected users. Once added to the list, you will receive email updates as soon as they already resolved the issue.
- Go to the Help (?) icon, then click Contact Us.
- Type the error you've encounter in the description field, then hit Let's Talk.
- Choose an option you want to use, then complete the necessary information.
To ensure we address your concern, our representatives are available from 6:00 AM to 6:00 PM on weekdays and 6:00 AM - 3:00 PM on Saturdays.
Also, know that you can always visit our help articles page for QuickBooks Online. This page contains a lot of topics about how to manage payments, sales transactions, customize sales forms, and other related topics.
Do let me know if you have any further questions. I'm always here ready to help.
