Hey keltiekoremoore,
I'm happy to see you're using attachments and the Receipts function to their full potential. Importing your receipts into QuickBooks Online is a great way to keep a backup of them, and having a copy really pays off in the long run. In this case, We could really benefit from having additional details and looking into account specifics. If the person uploading the receipts has sufficient access (at least a standard user with Suppliers access), refreshing the app data might solve the error: See your latest data in the QuickBooks Online app
If that doesn't fix the attachments, I strongly recommend using one of the following options to get in touch with an agent.
Phone and Chat: Click Contact Us to learn how to reach phone and chat support.
Schedule a Callback: click (?)Help in the upper right > click Contact Us > explain your situation > click Let's Talk > choose Get a callback (Note: Callback hours are the same as regular phone hours.)
Social Media: Facebook and Twitter from Monday to Friday between 9 a.m. and 8 p.m. ET
Let me know how this goes.
