So the new chrome update is launching soon (Check out how to handle the change). Chrome has launched it to it's Beta channel. Not live yet. I am sure will be a few weeks away, so you still have time.
I wanted to share with you a couple options so you can test how your ad will render in the new upcoming release with your current browser. Version 45.
Option 1 -
You can download the Beta version of Chrome from here. https://www.google.com.au/chrome/browser/beta.html
If you are on the latest version of Chrome Version 45.
in order to enable / disable this feature,
Go to Chrome Menu > Setting > Show advanced settings > Content Settings or shortcut link below: chrome://settings/content/
Then, Scroll down to "Plugins" (as per screen shot below)
Once you change the setting from "Run all plugin content" to "Detect and Run important plugin content" and you will start seeing the chrome bocker with 'play' button appear on each flash content / advert if they were not part of the main content of your platform.
