Sign-in no longer leaves you stuck

Two ways the sign-in window could leave you with nothing to press are fixed:

• When the Google button cannot load. Some browser extensions, security tools, and office networks stop Google's sign-in button from loading. The window used to show an empty box and stay that way. Now it tells you within a few seconds that Google sign-in is unavailable, and that you can continue with your email instead - your Google address opens the same account.
• When your browser fills in your email. If your browser or password manager filled in the email field for you, Continue could stay greyed out. It now always works, and if something is wrong with the address, Playcode says what.
