If I press map pinning then select a post code e8 for example there's meant to be 57 points there but there is only 20 points why is this?
Check the filters to make sure that the times asked is set low enough to include all the points.
There is no option for a filter. But there are points ranging from asked twice to asked 400 times so I'm guessing that shouldn't be the reason do you have any other idea?
