I am seeing a new problem. I built a project on my IPAD and then went to Windows to continue. The downloading takes for ever and never end up giving my the last update on windows side. On my Ipad, I exported the project to a Shapr file and reimported into a new project. That new project got quickly synchronized correctly on Windows, but the original is still not downloading. I a made a duplicate this morning on my Ipad to test a variance in the design, and that got synchronized correctly on Windows. So the orginal is not going though the cloud correctly.
Day later, it synchronized correctly. Go figure
