Finding old version of alexa skill

I have had alexa integration running really well in Singapore for some time now and I’ve been tasked to set up my sister in laws automation with alexa.

How can I find the version of alexa skill I am running and how do I install the same version? I’ve seen that the Aussies are having trouble with thiers

Mine says devUK and obviously I want to install the same in my sister in laws place.
