Its 3:45am and I've been sat here for hours trying to figure it out. I'm so confused I could literally cry.
1. From the inventory tab, I created an ad unit named x_y_z. Size: 300x250.
2. From the orders tab, I created a new order abc. Inside the order I added a new line item called abc_line. It's set to allow inventory sizes of 300x250. Start immediately. As a test I used type: Standard, 1,000 clicks at £1 each. In the inventory filter I set x_y_z and hit save.
I then added a new image creative, a banner with a simple external image and click-through URL. Target ad unit size 300x250. I then approved order abc. abc_line now reports "ready".
When I click on my inventory tab, I click x_y_z it says it's "active" and see the settings as mentioned above. But when I click on the line items tab, it's empty and shows "There is no data for this view."
I've got the tags for the campaign and added them to my website, I wasn't expecting to see my ad, because of the line items being empty for that ad. Sure enough, it didn't work. All I see are Google ads.
Why is the line items for x_y_z empty? Any direction at this point would be fantastic, besides giving up, I'm out of ideas.
