Recently implemented Google sign-in in my local dev. Everything works fine, except when I choose one of my Google accounts to log in, the consent screen does not show up. It does get authorized, as I can see my website in Apps connected to your account section of My Account.
I have already configured OAuth consent screen under Credentials section of APIs & Services console. Not sure why it's not showing up? I tried sending approval_prompt=force but it had no effect. Also tried prompt=select_account+consent which give me an error.
Some addititonal info:
