Cant seem to get Reactions plugin to work

Hi,
Firstly forgive me if this is NOT the correct place to post this request but I figured it made more sense here than the dedicated plugin topic.

I have a pretty new install and have been experimenting with official plugins and found the Reactions plugin which I have successfully installed & configured :grinning: the issue I am having is nothing shows up on a post (no heart etc) and I want to try and get to the bottom of it and make sure it works.

I understand this is a big ask but I use a β€˜clean’ version of Chrome (no extensions installed) and using the same browser I see the correct action of the plugin on the Meta site/topics. So my basic question is where should I start to look to debug this?
