Checked on Garmin Express, and noticed that an update to Firmware Version 6.0 is available, along with BTLE, Sensor Hub, and something else was available. Anyone got the changelog so I can see what I've done to myself?
Can you get GE created Routes to appear on the watch?
Yup, working fine. As a further test I just created a new route in Explore on my iPad, added to the collection that syncs with my 5+, synced with the Explore servers, then opened Explore on my iPhone and synced Explore with my 5+. I then opened the Navigate app and went to Courses and the new Route from Explore was there (with a stupidly long time, but that’s a known issue I believe). You mention going to Navigate and then Activity (rather than Courses), that may just be a writing mistake but if not that would explain things (Navigate Activity looks up your past recorded activities rather than Courses).
I select the Navigate App ( meant app before, not activity)...then Courses...the only option in there is 'Create New'....is this the menu path you are following or am I missing something (a new user!)
