Blender 2.8?

Installed the Chordata add-on to blender 2.80.

I activated the add on but couldn't find where the "Chordata tab" is. I've now updated to blender 2.81 and I still can;t find the tab.

This is the only reference to Chordata I can see in the blender UI:

Any ideas?

Just tried 2.79 and all working as expected.

I saw this on Facebook shortly after I posted this thread! 🤣
