We've been using the same link for a while and never had any issues with it, so this is a relatively recent issue. There are 2 of us that are experiencing this same problem.
So the option to change from development to any other "View setting" is greyed out. I simply cannot alter the same link. When I try to create a new one it just loads forever. I left it at 57%, when I came back 30 min later it was at 53%
Sorry to hear you are having trouble using Adobe XD. We would request you to please try the same on a different machine, also could you please try copying everything from the prototype mode and paste into a new document and then try to share the link?
No diagnose or solution here, but I'd like to add that I can –still– easily swith my shared version from any kind to any other kind. The initial version defines whether it will reside (and remain) in this "view" or "spec" part in the URL, but that should not pose any problem. What type does the Manage Links overview tell it is, because that indication should change instantly and accordingly ?
