Well I tried to search for Google Play Services APK on the
SC via the downloaded Brave browser and this time I found one and it installed - which seemed to make many of the other apps happy with respect to finding location services.... think that was trick - or, it may have been changing the location source to GPS - not sure.... changed too many things at once - doh!
I did successfully install and use (with some minor annoyances of landscape vs portrait rotations) the following apps:
Sync
Voice Recorder
HD Sync (AirData)
Brave (browser)
Amazon AppStor
Amazon Music
Amazon (Tablet version)
Apps that all worked when 1st installed Google Play Services - then I shut down the Controller, started it back up and now they say App Services are not there or have some error
KittyHawk - crashes when trying to access the map
AirMap - says Google Play Services are not supported by the device
SkyWatch - error about Google Play services
FlightRadar24
UAV Forecast - can't find location
Is there a specific version / link to a Google App Services APK that I should be using?
