There are dozens of P3s with connection issues on both iOS and Android. The P3s were shipped without the Pilot Apps even working... both Android and iOS had to wait for firmware upgrades.
I agree with you regards live streaming. I will never use it unless I am filming a wedding which is being broadcast to YouTube or a special LIVE event. Even then, I also don't think live streaming will be reliable enough to guarantee as a business offering.
If you watch all the unboxings, you will also note how many gimbal supports fell off when the P3s were removed from the box. Personally I suspect many of us will have a gimbal issue later because of the poor packaging.
I contacted a company who works with DJI regards software development using the SDK. As I suspected, it is still not complete. So some programming is still not possible.
DJI have over delivered on many aspects... but they have over stated on others... The fact is many people with recommended devices are struggling to get it to fly as intended...
So to suggest it was rushed to market is not reaching to far in the conspiracy realm
