After having a discussion with support (ticket number is 00759959), I would like to submit a feature request to allow controlling Invitation flow with support of parameters
screen_hint in the same way as Login/Signup flow does, New Universal Login Experience.
Currently, when an existing user accepts an organization invitation, Auth0 defaults to show Sign Up prompt. The user doesn’t notice that it is not Login, and, when they enter their credentials, an error “Something went wrong, try again later” appears. This creates a broken user experience.
There is no workaround for this issue, unfortunately.
