Hi Luis,
For us to be able to assist you better, could you confirm if the issue you
are referring to is in the AdWords UI or AdWords API?
If it's with the AdWords UI, then it would be best to redirect your concern
to the AdWords Community forum
By looking at the campaign level the report shows some impressions lost due
to ranking.
Problem is that when I look at the group level the lost impression share by
ranking does not show.
Any idea why? This happens on all accounts under my MCC.
Attached you will find the corresponding images.
