Hi, I have been creating new scenes in SketchUp, however, the scenes in the thumbnails have a question mark. I have updated it but the “?” it won’t update. This is working fine when I do a flythrough. Any help on this would be appreciated. Thank you

Could be the thumbnail is turned off.  
Here (in french), when I right-click on a scene, I can ask SU to use scene thumbnails.

if I select all my scenes, and tick it off, I get grey squares with an ? on it.

not sure if the thumbnails auto update live, if so, turning them off could save some computing power, especially on a heavy file with lots of scenes ?

Thank you very much - the updating first option worked.
