Transfer gpx route files from Android phone to Zumo XT using GarminDriveApp

[An9dy]

I had encountered failures to transfer gpx files from my Android(Samsung) device using GarminDriveApp, failing to transfer the gpx file to my Zumo XT SatNav.
The solution is you MUST ensure you update GarminDriveApp (on your phone) to version 4.16.26.
Also in MRA, the best gpx file format to save (for Zumo XT) is "gpx (BETA, route,track, POI)".
