For a few days now, the Geo heatmap chart in my looker studio report has stopped working. When I first load the report, the space where the map should be is blank. When I change the dates, the map loads but without any data. Sometimes I am also getting a 'System Error' message. I've used different computers/refreshed my cache and I still get the issue.
The dimension used for the map is 'lat/lng from query string'. I've checked the google source (google analytics) and I can see that we are collecting this data. I've also checked the calculation used to calculate 'lat/lng from query string', and everything looks correct here.
Is anyone else experiencing this problem? Or can someone recommend troubleshooting tips?
