DJi Phantom4 pro v.2 failed during start mission

We have DJi Phantom 4 PRO v.2 and we use Px4d capture for 3d model creation.
Now we have big following issue:
After we connect to Dron, load the Mission up and press the 3 second start - Dron takes off up until 2 meters height and stays there!
The app does show any error messages, it keeps saying that “Taking off…”
We have tested this with more Tablets, but same results, we have done all updates and calibration of the Dron again, but no help.
All tablets we have used are Android.
Any idea why this could happen?

Thanks for help
