I've shared a Read-Only link to an interface with a coworker but when he tries to access the interface he gets a message that says "Unable to request access to interface". He tried deleting his account and recreating it, but he's still getting the same message. I can't see any reason why he wouldn't have access. I even got an email about the $10 credit I received when he joined. Why can't he access the interface? I'm on the Team plan, in case that matters. I've got roughly 18 collaborators, most of whom are read-only.

Thanks,

Kelsey
