From the MyDrive phone app, I am trying to send a planned route to my GO Premium X. Until recently, it worked fine: put in an address, send planned route to device, and away we go.. .and, then it stopped doing anything. I plan a route and press send to device and all I get is a message to say 'synced with MyDrive.' The way markings are never delivered.. .is this pilot error or has something gone wrong?
