Thanks for reaching out, @jw_priority1,
Currently, we have an ongoing investigation (INV- 57108) about custom messages not showing on the invoice. Rest assured that our engineers are working diligently to get it resolved.
I recommend contacting our Customer Care Support team so that you can be added to the list of affected users. This way, you'll receive email updates of the investigation's status and be notified once it's been resolved. I've included the steps to contact support below.
- Click the (?) Help icon in the upper right-hand corner of the Dashboard.
- Select Talk to a Human.
- Enter a short description of your concern and press Enter.
- Click I still need a human.
- Select Contact Us to connect with our live support.
- Choose Get a callback.
These instructions are also available from our guide: Contact QuickBooks Online support.
Please let me know if you have further questions or concerns. I'm happy to lend a hand. Feel free to reach out to the Community at any time. Take care!
