Yes, I did report this awhile ago. Inventables just got back to me. Here’s their response:
The project isn’t publicly shared by the owner. There is a checkbox users can check if they want the project to be shared with the public. They would need to check that and save it. Here’s a screenshot (attached).
Unfortunately since this is a customer’s project, they are they only ones capable of making the project public. You might consider sending them a personal message to see if they can check that box.
Could you check the settings on the project?
