Unable to share AR project, just refuses to create link

[nnnnnnnnnnnnnn***********]

No matter what I try, unable to create link to share my AR project. I've seen threads about corporate accounts and sharing settings but this is a single user account. Any help would be greatly received, I have an urgent deadline in 2 days time. 

It's not model complexity, can't share even a simple cube. It's the share process/mechanism itself.

Same issue! What gives?

I'm experiencing the same problem. I didn't notice a few days ago, but suddenly my project couldn't apply changes to my shared link. I made a new project, with simple local Aero assets, and I can't create new links.
