Lost access to files

I have project with a lot of files:


but none of the files are available and activity tab is empty.

If you click on SketchUp under Name what do you see?

The free plan automatically creates a Trimble Project that is called ‘SketchUp’ .
Files or ‘Models’ end up in that ‘Project’

A Model is not the equivalent of a ‘Project’, per se.

There was nothing:


Activity was totally empty as well.
Also trying to open recent model was failing and it was written that the file was deleted.

But now all is back, probably it was temporary issue.
