Delete Trakt cache?

I’m getting the Trakt API 42x (x=something) error. One suggestion on the interwebs said to revoked authorizations, and delete Trakt cache.
How do I delete Trakt cache?

I’m guessing you mean on the app? If you android, go into settings, search “apps”, find trakt. Click on it.
Then scroll to the bottom and click “clear cache”
