Mobile expense report only accepts one receipt attachment per expense

Description:

There is no way to add a second attachment to expenses via the mobile expense report.

Create expense via mobile app. Notice that once a receipt is added, the only option is to view the receipt. There is no way to add a second page or attachment. Add a receipt via the mobile app and attempt to attach it to the existing expense: 

Notice the only option is to replace the existing receipt: 

Select No and nothing will happen. Select Yes and the new receipt will become the only receipt: 

Expected results: There should be an option to add multiple attachments when there are multiple pages to a receipt or other scenarios (as is available in the web app).
