Sketchup 2019 all of a sudden stops authorizing me to use my active current account. Why?

Why mid project did sketchup 2019 stop allowing me to open files? My account is current

What happens when you try to open a file in SketchUp 2019? Can you start a new file in SU2019? Do you have a subscription license or a classic license?

I have an annual license and now it will open. I swear I waste more time on basics than on actually using sketchup!

With the annual subscription you have to sign in again every 28 days. Maybe it was just that time.

I was already signed in. Not sure why I was booted off?
