Google Identity Services
Google sign-in needs upgrading.
One or more of your web applications uses the legacy Google Sign-In JavaScript library. Please migrate your project(s) to the new Google Identity Services SDK before March 31, 2023.
At your earliest convenience, migrate to the new Google Identity Services by following the migration guide https://notifications.google.com/g/p/AD-FnEyIyeoYKdydXaPAMcuuzaawjP3y0gM7TwzpXChLgx3X2Xz4SKTR-4wEhry1iZ1DxJ4TaD504ntuXzcMkE50nh3Y20YQr1X23dvUHS_LznssfohzZm3M_eP9gsCLv_MJaQ0V6Q.
