Adobe sketch - no access to my projects

Hi there,

I lost my files from Adobe Sketch. They were on my iPad, but since last week, I have no access to the app, so I cannot see my files. In Adobe Fresco, I can see my last project, but the others are gone. Are they lost forever, or can I recover them somehow? I don't find them on the Creative Cloud nor on iCloud. Please help!

Thanks!
