Booking a birthday party and sending invitations takes forever because there's no back button. So do not navigate to any of the policies to figure out what they say. Don't click on other options or outside links for invitations because they may lead to a deadend and they may not have a back button. Thus, you won't be able to go back to the page in which you were working. When you hit the back button on your phone, the app will just send you to the redeem points page.
