You’re right. That last post is confusing.
Some Google accounts are part of businesses/organizations (mine included). There are settings that the administrator of the organization can set for third-party apps access to Google services (like GoogleDrive). I’ve seen situations where administrators have disabled access to GoogleDrive for users and iRhino 3D can’t access the files. I don’t think this is the situation in this case, but I’m not sure.
I think I might also have some bugs (in my code) that are region-specific…these would likely be all on my end, but since I sit in a specific region I have a hard time reproducing and testing these.
I’ll look into this more. Thanks for reporting this.
