We have just observed what appears to be some updates to Munchkin.JS that have broken the Marketo integration in our testing environment.
1. A variable we rely on window._MchSingle is no longer present
2. Some new variables are defined, eg: window.Munckin
Could you please confirm this? Is there somewhere this is documented? Because we observed the changes after spending hours trying to debug the issue. We were hoping to do beta testing with a Marketo customer of ours today when we realised this.
