Hello. I had initially authorized my app to upload files to its own special folder in my account, and then I disauthorized it for testing purposes. After that, I was never able to authorize it again. Whenever I go to the corresponding "https://www.dropbox.com/oauth2/authorize" URL to authorize it and click on "Allow", I get a 500 error.
I noticed that when I click on "Allow" a request is made to "https://www.dropbox.com/1/oauth2/authorize_submit". Isn't that endpoint from v1?
