The most recent time, the drone was only a couple of metres from me and just out of reach. The battery was around 80%. As the WiFi is sooo slooow now to find, the drone got fed up/worried and initiated its Return To Home sequence by rising up to my preset height of 10m, flying back over to the launch point and then waiting at full height (10m), presumably until, I either re-connected or the battery was low enough to initiate an auto land.
