That's because GrabCAD Print supports all Autodesk Inventor versions up to 2018, so 2019 isn't supported yet.
This is the list of supported file formats, see it:

Easiest thing to do until the update of supporting 2019 files is to upload stl files. Those are supported by almost all 3D printing applications.

Yeah, the newest update of GrabCAD is no better than the last one. I prefer using other ones to this.
