Google Chrome have now defaulted to blocking Flash content in an attempt to move away from use of the retiring platform.
YUDU are working on an alternative to the Flash overlay editor and will replace it with HTML5 in the coming months along with lots of nice updates to make working with Publisher even easier.
In the meantime, if you are using Chrome and happen to be presented with a message blocking you from using the Overlay Editor – please follow the link in the message to your browser settings and change them as so;
Changing to “Ask first” will automatically add an exception to the “Allow” list.
If you continue to have any problem please contact firstname.lastname@example.org for further assistance.
