Edit: got it to load! I need to set the list public for it to work here. Private works for the other add-on. As soon as I did, I went back into the settings and put the list again and it seems to be updating on first run. Let's hope that it can update regularly!

Oh you're right. For some reason Trakt is giving a 401 unauthorised on private lists even though it's authorized. Really odd. I wonder if I've missed passing the authorisation token somewhere or if its an error on Trakt's end

EDIT: Yep, I messed up something on a recent update and missed an authorization condition. I was sure I'd had private lists working in the past!
Functionality to use private lists should be restored in v5.1.52 that I just pushed.
