According to this link, I'm trying to understand why there is not AAM signals from AA on c_state, c_long and c_latitude on Data Signals dashboard.
Is there any additional settings that should be done in order to see this variables?
If getting lat and long values is really important then you can consider implementing AA plug in: getGeoCoordinates to and get lat and long values in an evar.
Alternatively, AAM has platform keys that you can use. Please note that you will not be able to see these platform signals in Signals Dashboard
