Where did my saved file go?

I’m brand new. I just opened up a free account this morning before work and played around for a few hours. I was proud of the model I created of my kitchen. I clicked save and when prompted to create a folder I did. I saved my file under “My Projects” as “Kitchen”. I didn’t think it was to my PC (and apparently it wasn’t since I can’t find it there either) so I assumed when I started up SketchUp online again I would be able to click Open and load it from wherever it saved from.

Unfortunately when I click open, there’s nothing there. Is this a Beta glitch? Did I do something wrong and my model is lost forever? Regardless, from now on I think I’ll download my work to my PC.

Would appreciate any help finding that first model.

Thank you in advance.
