This is a bit basic for the experienced Pilots I suspect. I don't have my Drone yet, but have tried to download the Mavic Air 2 DJI fly app in preparation. I am having a terrible time, download not working, phone blocking its installation and a couple of other errors. Maybe my 3 devices, Huawei P9 lite, ASUS 7 Phablet and Samsung GalaxyTab 4 are simply too old and under spec to do the job. So, which of the Mavic fly apps is the correct one for the Mavic Air 2 would be my first question, and if my devices are unusable and my eyesight really needs something larger than a phone, what are the cheapest options available to me, 70 years young and the pension will not buy me a £1000 device. Thanks Pilots.
