Admob, Unity Ads, and Google Play Services

Hi guys. It seems to be a conflict with Admob 2.3.1 and Unity ads after getting Google Play Services to work. At first i got Admob 2.3.1 and Unity Ads working perfectly then once i placed in Google Play Games services, none started to work. Therefore went to online forums and found out that 0.9.27 kept deleting the "lib" folders etc, so i got that sorted! Now Admob and Google Play Services were working perfectly but my Unity Ads stopped showing. They would work in the editor mode but wouldnt work once deployed to Android Device.

Anyone has the latest Unity Installed with all the Google Admobs, Play services and Unity ads all working together? Would be good to hear what version Admob, Play services and Unity Ads all function together as i want to update from 5.2.1 but can't as i can't find a stable Unity version for my projects to update without there being any conflict with one another.
