Here is the documentation for adding a new member to a project—pretty simple. However, when I add a new member to the project, I get an error:
Error
The specified invitation was not found.
The member I'm adding is an alias account. When I say alias account I mean my main account (username@gmail.com) owns the project, and I'm trying to add a different email that I own (me@mydomain.com). me@mydomain.com is a sub account of username@gmail.com.
When I click the confirmation link, first I have to type in me@mydomain.com's password, then I am redirected to type in username@gmail.com's password, and finally I am redirected to the project where I get the ugly error staring me in the face.
I would be talking with google right now if I could, but I'm a bronze member…
This answer explains that if I want to change the email that displays on the oauth permissions screen, I need to add the email to the project. I'm trying to add the email to the project so I can display me@mydomain.com instead of username@gmail.com on the oauth permissions screen.
