To answer my own question above.
Short answer, the plugin was logged into the wrong YouTube account
Long answer
When I log into YouTube, I see 2 accounts, my google account and a youtube account.
The first time I connected the plugin to my account via google.com/device I had selected my google account and not my YouTube one.
Switching this account resolved the issue.
