Some online map providers may stop working, so we must remove them.
Also some online maps may not have data everywhere in large zooms.
The app cannot control the online map providers and how often they update their maps.
Please prefer the offline maps which are always better and are updated more frequently.
Note that the routing is not related to the maps. The maps are used only for appearance.
