How do I ask to join a buddy's Plan?

Tap a day on your Schedule calendar, then tap Ask to Join next to a buddy who plans to go out that day. You can also tap one of their days under Next two weeks on their details screen. Your request shares only what you already see: the day, time, and length of their Plan. It shows as Asked until your buddy invites you, you withdraw it, or the Plan starts; tap Asked to withdraw it. Asking closes two hours before the Plan starts, and you can have up to three requests waiting with each buddy. Your buddy is alerted only the first time you ask for a Plan, and for at most three requests a day. If they move or remove that Plan, your request is withdrawn for you. Asked shows only on the device you asked from. When your buddy invites you, answer in the notification bell on Home. If you choose Going while you already have your own Plan at that time, one-time or recurring, you can replace it for that day so your time isn't counted twice. A recurring plan keeps going on your other days.
