I'm trying to map data that I uploaded with an csv file. Originally this data set only included the country code, e.g. BD, for Bangladesh. I tried to geocode it by admin region and selected the column where the country code is stored. It gives me an error message.
Then I updated the data file with more specific information on the location: address, city and country. But this also did not work.
What do I do wrong? Should try it with long and lat values?
Is there a basic tutorial for newbees like me?
