currently I use MapFactor on a Lumia 650 with a Windows 10 Mobile OS.
I bought about a year ago Tomtom-Maps and it was working, if I now click on "update / buy new map" I got a error message "Map Factor: Not available in this application release". In Settings, App, "about MapFactor" I see a Version Information with 1.1.7.2.
Is MapFactor abandoned for Windows Mobile OS? It seems, that this is the only getable version on the store.
