Hello,
I keep getting an error when trying to add an external email to a hub as an editor… The global setting for external collab restriction is off as is the setting for the hub.
I have also tried adding the email to the folder as an editor and then the hub with no luck.
Hi
We’ll look into the issue further. Could you please share the exact error message you’re seeing when trying to add an external user to a hub? Also, does the error occur with other external users, or is it limited to this specific email address?
Thanks so much — we look forward to hearing from you! 
Thanks for the warm welcome! I have attached three screenshots, any email address used.
