Expected behavior
Users should see some kind of authentication success message and an instruction to go back to their device, rather than end up slightly confused that they're now at their connections page. They'll likely go back to their device eventually, but this still doesn't feel like a good user experience.
Additional context or questions
I'm using this flow for a desktop app, where users would open the activation URL in a browser on the same device. Because of this, the desktop app may not be in view after successful authentication, so the user might not notice that they are now logged in on the desktop app.
Brief description Users aren't given any instruction or success message after authenticating, which could leave them a little lost.
How to reproduce After authenticating using the device code grant flow, users are simply redirected to https://www.twitch.tv/settings/connections.
