Two sign-in fixes: no false error after a successful Google, Apple or Strava sign-up, and no false invalid code message after a correct email code
Sign in and sign up
Signing up with Google, Apple or Strava could end on an "Authentication error" page even though the sign-up had worked and you were already signed in. When that happens now, you go straight to your workspace.
If a sign-in finishes in a different browser from the one it started in, the error page now says so and tells you to start again in one browser. Before, it showed a general error message.
After you enter a correct email code, the code field and the Verify button stay off until your next page opens. Before, a second press of Verify sent the used code again and showed an "invalid or expired code" message next to the success message.
A correct code now replaces the error message left by an earlier wrong code, so the two no longer show together.
Account settings
Changing your email address with a code has the same fix: a correct code is only sent once, and it clears the message from an earlier wrong code.
