Resolved the issue. This was a network issue as my office network didn't allow me to update the design to Adobe's server.
So used my home network and created the link.
Note: I am able upload my XD file to the Assets page, but not my prototype from XD!
Thanks for your reply.
Glad to hear that it was resolved! Please let us know if your admins want information on what you will need to whitelist in order to get sharing working from the office.
I am having the same issue - can you tell me what to whitelist?
Same "error 69" at my office. Can you let me know what to ask I.T. to whitelist as well?
Also, could you let me know if there are any alternatives to whitelisting for uploading XD prototypes? (Our I.T. dept. isn't always very receptive to creating exceptions to their rules.)
