Game freezes after ad closed

Hi,

I have tried several advertising networks recently and on a few i have noticed a delay closing an ad and continuing the game. The game just freezes for a second or 2.

Im currently trying out AdBuddiz (been the easiest to integrate so far) but it seems to freeze more than i have noticed on other networks. Mobilecore had no delay and the game continued straight after.

Has anyone else experienced this? Am i doing something wrong?
