I get the screen frozen on "Signing in..." when trying to authenticate with Github.

I was trying to sign in with Github with this account (@carloslfu).

It's weird, it sometimes happens and it sometimes not. Right now, I'm not able to reproduce. But I noticed the button doesn't change when you "sign in with Github" from a sandbox (sometimes).
This might be related to the recent GitHub downtime, we'll need to keep an eye on it.
@carloslfu Does this issue still persist? Can we close it?
Closing this, as no complaints since last comment.
