Do the Fenix 5 models, especially the 5X, support PersistedContent route/course downloads and Intents? On the simulator the methods appear to be present in the classes, but when I try to download a route (using code that works on the Edge and Oregon/Rino), neither :responseType => Comm.HTTP_RESPONSE_CONTENT_TYPE_FIT nor Comm.HTTP_RESPONSE_CONTENT_TYPE_GPX appear to be working.
Thanks to the help of some awesome testers (lucky new Fenix 5 series watch owners!), I've been able to verify that FIT format persisted-content works great on the Fenix 5, 5S and 5X. Our routeCourse app was just updated to support the Fenix 5 watches, and also the Forerunner 935.
