title: Firebase sendSignInLinkToEmail taking ages to send email to user
body: <p>Hi I am currently using firebase's <code>sendSignInLinkToEmail</code> to send a passwordless sign up to a user so they can authenticate. However, currently it is taking a minute or two to send an email to the user. I was wondering why this is and how I can increase the speed at which it does this. Thanks all help is welcome.</p>
