Hi Davina - I think we may be talking about different parts of the receipt management process.

We have no issue uploading receipts via the app and we are not emailing receipts. The issue is with selecting the customer/project in +Add customer, which is under Optional fields during the receipt upload or editing process.

If you can see in my image upload - when I tap +Add customer, it takes me to the list of our customers and projects, however when I tap on one to assign it, I'm kicked back to the Optional fields page (image below) without having added the project I selected.
