Link Tab

I'm having this issue when trying to sign into my google account to use the link tab tool where the authentication prompts this : Sign in with Google temporarily disabled for this app This app has not been verified yet by Google in order to use Google Sign In.

@lougallo I have used link tab and found it useful for me, however, when I recently wanted to use it again, it kept popping the same window out even after I granted the permission numerous times. Can you please have a look?
