It seems as though trakt have very recently disabled a number of API keys, which impacts a bunch of our favourite banned addons, as well as the official addon trakt list manager.
I have verified this by creating my own api key and switching them in the code.
I don’t know who looks after this addon but figured it was worth mentioning so it can be updated or the api key can be reactivated etc.
I also really enjoy having a laugh about those other addons which will basically stop working (at least the trakt integration part)
