I have a M7 pro robot and it periodically loses the stored map and therefore it subsequently needs to perform the mapping again. This also implies of course the loss of exclusion zones etc. In addition I can't find anyway to restore a map. In the app the only option is "Reset map" ("Reimposta mappa" in the Italian version) but when I click it, it simply erases the map (if present) and does not show any map to load and therefore it starts a new mapping. Any advice?
