Hi, We have been using sketchup for schools with our G Suite for Education Domain for about 3+ years. in the last couple of days we have begun to get Sign in errors, with the result looping back to the message about Sketchup for Schools is only for educational use. it then asks us to log in again. Our school domain is maffrasc.vic.edu.au
It also did the same with my Department of Ed account which the domain is education.vic.gov.au
Can you check this domains are in the whitelist please.
