Does the model load on the platform and create any geometry for export? Did the email export work before? Any more information as well as model link would help us to troubleshoot this.
I am receiving the emails via the embedded model on our web page. However, when I click on the received link to download to my machine, the error message occurs in my browser.
I’m really sorry but you discovered a bug, the email export links should last for 1 week. Thank you for reporting the issue and my apologies for any inconvenience. We are working on a fix which will be rolled out in coming days.
