I have been invited as a collaborator but unable to see the project on my dashboard. What’s wrong there?
Make sure the email address, you are invited with is the same as the one with which you are trying to access it. Other possible reason might be that the owner has archived the project, or might have exceeded the number of projects limit. Also, might be for some reason either the project is deleted or you may have been removed as a collaborator for the project.
The exact email address can be checked at the 'Edit Profile' page. To access the edit profile page, navigate to the drop-down adjacent to your profile image and choose the edit profile option.
