Hi
I'm quite new to the AdWords API and I'm experiencing a problem uploading a user list.
I followed the AddCrmBasedUserList.cs example in order to create a new user list and populating the members. My list has apx 57000 email addresses, and mutateMembersAsync returns no errors or exceptions. The list is successfully created and I can locate it in Google Ads.
The problem is that the list contains no entries. After creation it says "Populating" for a while, then it says <100 Too small to serve in Ads UI.
The mutateMembers result object also has a property size and sizeRange that indicates that the list is empty.
Is there a way to figure out why my members are being rejected? Or anything obvious I'm missing here? I've attached my method source code.
Thanks
Snorre
