I started a new PPC campaign this month and all my google /cpc sessions are recorded as (not set) / (not set) in Source / Medium report.
When you click a ppc ad, you can see gclid in the address bar and in real time reporting it shows correctly as google / cpc.
But, under adwords tab in analytics account, it only shows the clicks and zero sessions.
2 accounts are linked correctly and auto-tagging is enabled in adwords.
Any help, idea or suggestion to investigate more regarding this would be highly appreciated.
Thank you very much.
