I need to give access to guest that needs to get inside my apartment (self check-in for b&b). I add the new shared user (guest option) and set the access duration. When I send the invite from the app, the guest can create an account but, at the end, he has not the option to accept the invitation. On my app I see the guest as "Invited". I need to resend the invite and then the guest is able to accept the invitation and unlock the door. Am I doing something wrong? Is it possible to check this procedure. I have already called the support and I am waiting for an answer from the engineering team
