Thanks for reaching out. There are two ways to open a prototype directly on the Adobe XD Mobile app, the first one would be to do a live preview using USB tethering and the other one would be saving the file as a cloud document and then opening the file directly in Adobe XD mobile device.

Let us know if this helps or if you need any further assistance.
Thanks, I'm aware the two ways you describe. But my Client needs to preview my XD Prototype on his device in the XD App.
Any solution for this?
Anyone knows how to preview a XD Prototype on another device in the XD App?
I am so sorry for the delay in response, Iwan. In this situation, you will need to share the actual file with the client and to preview the file on his device, he will need to add that file to his Adobe Cloud storage and once it's saved there your client can open the file from XD app installed on a different device.
