I was trying to fly my spark off the beach at sennen cove last summer but because it was near (about 3miles) to the airport the dji technology would not allow it to take off.
I have had to revert back to dji4 app. 4.1.15 and the firmware that was in use a year ago using assistant 2,to allow me to carry on using my huawei lite 8 smart phone, dji' solution was get a new phone which I cannot afford to do.
