On apps.twitter.com, when creating/editing the permissions of an app, there is a link with more info about the permission model. It links to the old docs and clicking on it results in a 404.
Should link here: https://developer.twitter.com/en/docs/basics/authentication/overview/application-permission-model
Thanks, we will need to put in a redirect to handle that, but I’ll put that on our list of fixes.
