That’s part of what’s odd. The Onedrive toggle in the iRhino app is missing, but I have it in Files.
I’m kind of starting to feel like there might be something broken with either Files or Onedrive though. I can’t open .3dm file Via Files if it is in Onedrive, and the downloads from Onedrive to local don’t work. But I can open a file that has been downloaded from an email?
