Infinite duration in display advertising
In Cyprus the web banners of LIDL have no limit in duration and looping.
I asked adwords support team about this issue by sending them a grabbed video (https://www.youtube.com/watch?v=4WyFXhyK2dI&list=UUxBWBt2xf4sxU-O4yQpYJdg) of the web banner and also the URL.
They replied to me saying that they solved this issue.
I then asked why that happened and they said it is not possible to have an answer on that.
After a few days I came across LIDL web banners and the duration was again infinite.
I send them once again an email but I never received an answer.
Is there a secret?
