after a few image asset downloads, my iCloud stops showing the downloaded file.

Hi,

This issue only started happening in the past few months. After downloading a few large image asset files from various stock image sites using Chrome, the files no longer appear in my iCloud Drive. I have to manually download them to my desktop and then move them into iCloud. I’ve checked my available storage, and there’s plenty of space. Chrome shows the download as complete, but the file is nowhere to be found. Sometimes when I'm downloading the file, it sometimes appears for a second and then disappears.

Any suggestions on how to fix this?

Thanks - Molly
