"POI will be a feature in upcoming firmware, waypoints will more than likely be from 3rd party apps."
Personally, I'm not holding my breath for anything from DJI. I'm sure we won't know for sure until it's actually been released. I think it's obvious that DJI released the P3 before it was completed. There are just so many things missing in the Pilot app. While I like that DJI released the SDK, I don't like that it appears they are just going to ignore what they told customers they would be getting. Keep in mind, these 3rd party apps are not free. They cost around $10. On top of that, there are no trials. You need to pay for the app to determine if it's what you want. 15 minutes is not enough time to download and use an app such as these.
