When I send a route to the device BaseCamp gives an error each time saying 'Routes sent to epix were recalculated because they was created on a map that is not installed on that device.' English needs to be updated there a bit was/were but this seems to be where the route breaks down and turns into a severely broken track with direct lines from waypoint to waypoint that span miles which is impossible to cross unless you're flying or hardcore parkour. Waypoints are also not shared, they are always duplicated for each route, however each route is converted to a track which is not usable since it creates straight line paths from way point to way point that even most hikes wouldn't work with. The only way I can delete anything is manually through the watch and with all the duplicated waypoints, this has taken over an hour just manually deleting. Two updates (while BaseCamp said the routes and waypoints were gone) resulted in over 30 way points because I have around 10-15 each route. If I pushed an updated route or route that shares waypoints, I also have duplicates of all my waypoints etc. When I disconnect the device, all is still there.

When in BaseCamp, if I delete items the Epix device internal storage, BaseCamp reflects this while the device is connected including syncs, adds, etc.
