Since the last firmware update my p3s will not properly connect to my iPad Air 2. Starts fine looks like all is well. Then shortly after it takes off says aircraft disconnected.  I am still able to control the aircraft. But lose video. Is there a way to revert to the older firmware. Or some other fix. Thanks for your help.

Just to clarify, the upgrading went smoothly, right?
Please try to restart aircraft to see if it works.
Also you can turn off aircraft, unplug the pin cables attached to gimbal, wait for a while, plug them in again.

The upgrade went smoothly. I unplugged the pin cable waited half  hour  restarteded still doing the same. Now it will flash from connected to disconnected when it is sitting on my kitchen table. Is there a way to down grade the firmware or re upgrade it.? could I have a hardware problem?

If in that case, the best cause of action would be to send it in for evaluation.
You can send both aircraft and remote in.
