Now that you jogged my memory, I think that's the same horrible problem that I had. Start the report on desktop, switch to mobile to add receipt photos, go back to desktop to fix up all of the stuff the mobile app can't do, and repeat if any of the reports or photos got messed up somehow. You end up in this insane loop of switching back and forth between devices with a pile of receipts on your desk. Nightmarish.
