The rain is gone and I have made a test with the Android version.
The google play daily version does not have the new features (it is from 2019/9/17), only the apk does.
Configuring follow me works great.
But at the field I could not switch to “follow”, neither from qgc nor from the transmitter.
Also “take off” did not work.
Unfortunately the log upload does not work, the log file is here
