Hi @Zipena,
Thanks for the reply.
I have reviewed your screenshot and noticed that the invitation URL appears as “https://app…com/”, which does not match your tenant name.
It should look like “https://dev05kn…us.auth0.com/”.
I suggest getting a fresh invitation URL, and modifying it to use your canonical domain (https://dev05kn…auth0.us.com). Afterward, try accessing that URL in your browser.
This should bring you to a different screen that would look more like the following:
Thanks,
Rueben
