Thumbnails preview cannot be seen in folders

How did this work exactly? The Windows App Store only appears to offer SketchUp Viewer for the Oculus Rift, at least in the UK it does. There is no option to install through the App Store to Windows without having that hardware connected/installed. I had to find the app by searching the Windows Store using Google as searching for ‘skp’ files within the Store itself doesn’t show the Viewer as available at all, even for the Rift. I did try installing it from the SU website but without any success as far as thumbnails go. In fact the Viewer doesn’t even show up in the list of apps when setting default apps for file types.

I have the same issue as everyone else but I also don’t get any file preview in the preview window in File Explorer. This whole issue is beginning to cause us major issues and is something that really needs addressing quickly with a bug fix/patch as soon the engineers can get to the bottom of it. Any updates on progress?

Update - I’ve tried it another way, by selecting SketchUp 2021 as the default file handler for skp files using the method Select file > Right Click > Open with > Choose another app…then locating and selecting SketchUp.exe, also tired with SketchUp Viewer. By doing this thumbnails (but still no previews) show up for all files saved using the 2020 file format or earlier. Any files saved as 2021 will not show up. I’m no software engineer but logic suggests this points towards a SU2021 installation/file type only problem. The software was installed as Administrator.
