Location is empty on Service

Hello,

I have a map visual which is correctly displaying all the cities on a map  in PowerBI Desktop(right now I only have city as a possible location indicator) however in the published report the map is empty. I've read that for many people if they've selected the correct data category even the publised reports started to show the data correctly but this is not the case for me. I've tried City/Place but none of them helped in PowerBI Service. 

Anyone has any suggestions how this could be sorted?

Thank you!
