1 pointHi @bhabanisankar, Google has quietly deprecated the library used for Google Sign-In, meaning that new integrations cannot be set up. We will replace it with the new library in the forthcoming v8.5.2 maintenance release. The reference for this work is CORE-17740. Once we resolve cases and push features they are available at our change log, here: https://changelog.whmcs.com/ I apologize for the inconvenience, and appreciate your patience as we work to resolve this.
0 pointsIt's not hard, WHMCS is actually quite easy. Its bugged? Yes, that is a completely different issue. In my experience, every new release introduces more bugs and problems than it tries to solve which means make sure to test, then test again and then re-test everything again before putting a new version in production. Even then you will find so things stop working or don't as before.
