Hi @Imogen1, welcome to the Asana Community Forum! If two people are seeing each other as a “Private User”, they are both Guests. You can still see them as Members in a project or Team but they don’t have the same domain associated to your Organization.
If you would like to get more details on why they are seeing each other as Private users, I recommend you to contact our support team and confirm the following information:
- Project URL
- Email address of both users
Hope this helps and sorry for any confusion here! Let me know if you have any other questions!
