My students can't log anymore using their Google account

Hello, since few days my students can get access to sketchup anymore, they have a sing-in error box, is it a general problem ?
Thanks

@wizstef Do you know approximately when this may have changed? There have been some recent changes within the Google settings that may be affecting your access, and it would help to know when the issue began for you.
In the meantime, if you’re able it might help to review this post regarding one of their recent updates.

Thank You, I have re-granted access to Sketchup in my Google domain an it’s working
