Mydrive Android Synchronization

I have a TomTom Rider 450. I use Mydrive on Windows laptop and also on Android phone.
I imported some GPX tracks in MyRoutes on the Windows laptop which synchronized fine with the Rider.
But I can not import or synchronize the tracks in MyRoutes on the Android phone. Can anybody tell me how to import or synchronize on the Android? Or is that not possible?
