Summary

Can you upload documents as an attachment on mobile?

Does anyone know if it's possible to upload documents on mobile? In the documentation we've found you can add "documents" but really this is just adding information for driver's license, passport, visa, etc, not an actual file. We were wondering if there is functionality to upload an attachment for things like benefits certifications (marriage certificate, birth certificate, etc.) that are needed for proof of a life event.
