Thanks for the additional information! 

I see from your post that you're processing the OAuth app authorization flow in a web view, not the system browser itself. Per the Dropbox /oauth2/authorize documentation, we do not support processing the OAuth app authorization flow in web views. (This decision was made in order to support the Google Sign In flow for signing in to Dropbox. That may still work at the moment, but Google has deprecated it, so it will stop working in the future.)

Further, you mentioned that it is working in Chrome, so it appears to be something specific to the Electron web view, so I'm afraid we won't be able to offer help with that anyway, as that's not supported.

That being the case, you should update your app to process the OAuth app authorization flow in the system browser instead.

Hey Greg,

Since yesterday morning I have experienced the same issue as leriano. I am using the .NET SDK and haven't changed any code (prior yesterday - everything was working), but the OAuth flow continues forever... When I click "Approve" it starts loading and then ..nothing happens.

On breaking I reach this call: 

var response = await DropboxOAuth2Helper.ProcessCodeFlowAsync(
                   code,
                   Global.AppKey,
                   Global.AppSecret,
                   RedirectUri);

It doens't proceed to returning response and I get no errors


Using Google Chrome Version 69.0.3497.100

    Hello TwinBlade!

    Does it reach your redirect uri???
    In Google Chrome 70.0.3538.77 for Mac OSX works great for me.

    Thank you!

      Hello Leriano,

      It redirects to my page, but on there is the method to exchange the code for the token, which is problematic. I updated Chrome today, but I am still having this issue.

        TwinBlade Are you processing this in a web view in an Electron app? If not, it sounds like this isn't necessarilly the same as the original issue in this thread. In that case, please open a new thread with the details of the issue you're seeing. You said "the method to exchange" "is problematic". Please elaborate on that, and include any error or lacking that, explain what unexpected behavior or output it gives. Thanks!
