iCloud is not working
I just installed Big Sur (clean installation) I define my Apple ID on the computer I cannot see my files stored in iCloud I have Desktop and Documents folders but they are empty. I can see the files in the Cloud if I connect to the WEB. This is the second time I see this problem, the first time with Catalina and I reinstalled macOS at that time, but I do not want to do that this time. Any Ideas?
iMac 27″, macOS 11.1
