Once Tinkercad is open, on my main pc, I can see all my designs but if I try to open any design (i.e. Tinker This) all I get is the Tinkercad logo and the rotating 'loading' arrows icon, if I click on new design it does the same thing.
This happens if I use Edge Firefox or Chrome browsers to access the Tinkercad website.
I can use Tinkercad ok on an old Windows 7 pc using Firefox browser.
Everything was working ok before I did a re-install of Windows 10 to get round a Windows Update error.
