For anyone using iPad, I have sent a report to admin. regarding the Games App. Adverts which have returned this morning. Even with the "do not track" switched on, this does not seem to fix the problem. Hopefully it can be fixed soon.
Update: The games app. adverts have returned with a vengeance. Ash emailed to say he was taking the matter up with his advertising agency. Have reported again today, but Ash is out of the office until tomorrow.
