Thanks for taking the time to post in the Community, @KamilS.

Just to confirm, are you using the Progress Invoicing feature in QBO? If so, this has been designed to default to the Airy Template. That being said, I'm going to submit a feature request on my side to the Product Development Team.

On the other hand, if you're just converting a regular estimate to an invoice, we don't have an exact timeline for when this will be resolved. Our Product Engineers are still investigating the root cause of the issue and continuously working to fix this as soon as possible.

I suggest getting in touch with our Phone Support team and providing this investigation number 28978 so they can you to our notification list. This will help our Engineers know many users are affected by the issue. Once added, we will notify you through email once this has been resolved. I'll also inform you here when we get the update as well.

Here's how to reach them:

1. Click the Help (question mark) icon at the upper right.
2. Select Contact Us at the bottom to connect with our support.

Thanks for your understanding while we look into this. Please let me know should you have any follow-up questions. I want to make sure everything is taken care of for you.
