iCloud for Windows Wont Sync (Read Only)

Here's the quick background: I have the iCloud service and pay for the 2 TB iCloud Storage, which I share with my family. 1.04 TB of the 2 TB is in use. I use my iCloud Storage extensively from a macMini, an iPhone, and an iPad. From these three devices, iCloud Storage works without problems.

I recently installed iCloud for Windows on my Windows computer (Windows 10 Pro v.21H2, MSI hardware, AMD silicon). I built this computer from parts primarily as a gaming system. The SSD has 1 TB capacity, with 250 GB free. This system is used for online gaming, so bandwidth is good.

I installed iCloud for Windows from the Windows Store. Windows Store reported that my computer met all system requirements; it installed version 13.4. In iCloud for Windows settings, the only service I've selected is iCloud. I unselected the other three services: Photos, Bookmarks, and Passwords.

iCloud Drive appeared in File Explorer; however, it took more than an hour for the file listing to appear. Now that the file appear, if I "right-click" a file, it takes more than 30 seconds for the popup menu to appear. When I select "Properties" the properties windows appears almost instantly.

From File Explorer I added one file folder and one 5 MB PDF file (within the new folder) to my iCloud Dive. I waited overnight, and this new file folder and file did not appear on my other devices. The status in File Explorer shows "Sync Pending."

I have assured system updates have been applied (except for upgrading to Windows 11), and I have performed multiple cycles of logging out/in, power on/off, and uninstall/reinstall of iCloud for Windows.

Has anyone had any experience with iCloud for Windows that may explain this errant behavior?

Thank you,

Mark
