I have the same experience with the map for the Netherlands. In my region, several new bike paths have existed for almost 2 years, but they are still missing from the Wahoo map. This week I removed the Netherlands map and added it again, but it is still the same map without the new bike paths. Meanwhile, these new paths have already been known in Strava and Komoot for a long time. I previously created a post about this issue here:

but I never received a response.
