On V1 contact profiles, if you go to add recurring tasks, we are given detailed options. Example: I set recurring tasks for the first Tuesday of February and have it recur for a few years. However, when setting an autopilot campaign or even setting tasks on a contact profile in V2, I no longer have the same abilities.
I find it very useful for when setting maintenance reminders with clients. I like to keep in touch with them and remind them of some home maintenance that should be looked after.
