When I generate the GA -> Traffic acquisition report I can see no data at the Session Medium and Source.
For example : (direct)/ (none) or (not set) / (not set). the rest of the table is OK and I can see the source URL or IP but most of the traffic came from the aforementioned.
I believe it is something related to "localhost"\hostname but I wonder where I can set any value that will help me to get better GA report?
