When creating an invoice for a billable expense, how do I get the documentation to populate on the invoice?

This issue is already under investigation, dawnjohnson.

We have an ongoing investigation about the attachments for billable expenses not flowing to the invoice. Please know that our engineer is currently working on it. We appreciate your patience as we investigate this further.

Has a fix been rolled out for this? I bill my clients on a Cost-Plus basis, so providing receipts is absolutely necessary. 

Note that the investigation is still ongoing. Our engineering team is still working on a fix. I'll provide further information about this.

We want you to know that the issue is still unresolved, and our engineering team is actively seeking a solution. If you have not yet contacted our support team, we advise you to do so to be added to the list of affected users.
