What a horrible app to use. Won't remember sign in, so won't show you appointments. You have got to download the app there is no Web interface to view a appointment that was changed by the vendor so you have got to download the app. Once I figure out what time the appointment has been chnaged to I'll uninstall and avoid all businesses that insist on using Booksy. Don't force and app on people have both a Web site and the app.
