3D Warehouse not working in Sketchup 2018

I have Sketchup 2018 and 3d warehouse is not working. It was working lat week!
Is this problem designed to force me to upgrade?

See:

It applies to 2018, too. As with 2017 you can still use the Components window or your Internet browser.

Not specifically to force you to upgrade. The change in Chromium is outside the control of Trimble. Might be considered the risk of using old, unsupported software.
