The first attempt was to save plans from the PC to the cloud, and pull those plans in from the cloud on to my phone. No good...my phone can't see those PC created plans. So Plan B was physically copy the files onto the phone. This I did...to the "Skydemon" folder on the phone, tried to open these on SkyDemon on the phone...couldn't see them. Plan C - create a dummy plan on the phone and save it locally, then look for where it was saved by SkyDemon...and copy the PC authored files there. This I did...but couldn't find the phone authored plan, in spite of the fact I could import it into the phone version of SD.
