We are using Panasonic Toughpad that runs on Windows 10 and I experience same problem, one of my layer will not load. It works fine on Android and IOS, but on Windows Collector I get the error that my layer has invalid spatial reference, that the Wkid or Vertical Wkid is invalid. Other layers with exact same coordinate systems can be displayed fine. Hope that this issue is resolved as I only have access to Windows tablets!
