@skifast12 It can actually sync a route phone to watch even during an activity. I’ve done that - created a new route in Suunto App using offline maps, synced it to the watch, and started navigation on the watch. However, as usual, there are bugs and this doesn’t work well. As @egika mentioned, sync of a new route works exactly once. If you need to sync another route after that, it will no longer work.
I think the desired behavior should be the following:
Can start and add stop routes unlimited number of times.
Can always push a new route from the phone and if “Navigate on watch now” function is used, that must replace the current route navigation. This will allow incremental navigation using the phone.
The 10 route limit on the watch should be extended, or perhaps at the minimum the oldest route should be replaced when a newer route is synced.
