Aye lads, just wanted to share my solution to this issue.
I created a test page and changed the UM default logout page to point to the newly created test page.
Tested to see if it works and it did. So I changed it back to the default UM logout page and it worked.
Honestly dunno why this worked but I think there must’ve been an issue with connecting the plugin to the logout page. Not sure if it’ll help you lads, but it worked for me.
Good luck!
