How often Niantic update map in Pokemon GO? [closed]
Solution 1:
They don't have a set frequency for updating is the short answer.
According to a AMA that Niantic did the following question was asked:
Q89: mogu squad - I have edited OpenStreetMap because the roads were disappeared on the scanner by switching from Google map to OSM. When will the editing result be reflected in Ingress?
A89: We are still determining the update frequency.
