I don't use Adobe Aero, but their Help page says you can bring in a PSD or JPEG. Instead of exporting to Aero from Photoshop, try one of those formats and Import it into Aero. Let us know if that works.
"You can bring in your own photos, layered files, audio, or other 2D and 3D content. Aero optimizes imported PSD, JPEG, OBJ, GLB, FBX, GIF, PNG Sequence, WAV, and MP3 assets for AR. You can also bring in assets from Adobe Photoshop, Illustrator, and Dimension."
