We are unable to login to SketchUp using our school Google G Suite accounts though in the past it used to work. We still have it allowed in Google Admin. When we click to login with Google it keeps returning to the login screen to try again. This summer reached out to you and you said you had to whitelist our school’s domain. Our domain is lhprep.org. We recently switched our web filtering system to Securly.com if that makes a difference. They work as a proxy so we can filter web traffic on and off our campus. Thanks for looking into this.
