Thanks for your feedback! We completely understand that it's not the most intuitive to require the guest to create and verify an account before you can grant them access, and we've changed the process for iOS users already. Now, to add a guest on iOS, you only need to enter their email to send them an invitation, and they will automatically have access after they create and verify their account using the same email address.
We are releasing a new Android app soon that will also have this feature, so stay tuned! Thanks again for letting us know your thoughts, and we're happy to say this feature is already available on iOS and will be coming to Android shortly. Thanks for the reminder to update the original post! - CANDY HOUSE
