candisplaybannerads jerks onto screen when ad loads

Question

I saw a few posts on this but neither seemed to answer my issue...

I have a menu at the bottom of my view constrained to the bottom layout guide so that when an ad loads using

self.candisplaybannerads = true;

the menu moves up as well. In iOS7 this transition is smooth and the menu slides up as the banner slides up. But in iOS8 the menu pops up to the new location and then the banner slides up smooth. Has anyone else experience this or know how to fix it. Thanks

Sample Project: https://github.com/jbestor/adTest (in the sample project neither iOS7 or iOS8 smoothly slides up).
