It sounds like you're trying to use an old version of the addon with WoW 8.x; you always need to use the latest from Twitch

Hmm okay it seems i already had the newest update, but i've updated again now to make sure. Will see if it fixes it, thanks!

I'm gonna take your unedited answer as 'it works now', which is great! 😂 I'm going to leave this issue open for a while in case anybody else is in the same boat. Thanks!
