I used flutter to develop the app, but there's no official sdk, so I used dropbox api, and when I created the app I chose "Permission type: Scoped App", and I used oauth2/authorize. When you go to log in, nothing responds in the browser, is this a bug?
The /oauth2/authorize page and login flow should be working for scoped apps. I just tried it and it is working for me.
We'll be happy to look into this, but we'll need some more information. First, can you elaborate on what you mean when you say "nothing responds in the browser"? Feel free to provide screenshots or a screencast if that would be helpful.
Also, please let me know the full URL of the page and the name and version number of the browser(s) where you're seeing this.
Thanks! That's helpful. It looks like the issue here is that the app you're attempting to authorize has team scopes, but the account you're signing in to is not on a team, and so cannot connect an app with team scopes.
Accordingly, you're being prompted to sign in again with a team account in order to connect the app. Normally, when signing in with Dropbox credentials, the page would show an error message indicating as much. This doesn't appear to be displayed when using the Google Sign In flow though. I'll ask the team to fix that up to show the error in that case as well.
