It's not that I expected to work on the PC I just want to be able to see everything else.
I have used other AdMob plug-ins before that didn't create this problem.
Usually plug-ins that are mobile device specific are ignored.
I am currently getting around it by removing the plug-in for the time being but there must be a way to circumvent the plug-in so I can keep it in there because every time I want to make a change to the game it means I have to delete the plug and then re-add it later which is ridiculous.
