Why is it that when I use TomTom maps, the route is recalculated—adding significantly more waypoints than I had originally defined—whenever I try to navigate it? (This only happens with TomTom; it doesn’t occur with Here maps.)

Previously, I could easily see which routes were synchronized and which were not. Now, there is only an option to synchronize all the routes I have in the planner. I preferred it when I could check the synchronization status of individual routes without having to sync every single one. Is this how it works now, or am I missing something?
