All Shared Albums removed on Windows with each reboot
On Windows 10, using iCloud 14.2, I have Shared Albums enabled. The issue is, each time I either reboot or even just log out of my user account, all the Shared Albums (folders and photos) are completely removed, then they start downloading again. This has happened over and over and over again on all of our household Windows PCs (both Win10 and Win11). Sometimes however, it takes a few reboots before they will start downloading again. It eventually completes but they all get deleted again the next time I reboot or log out.
I can see ApplePhotoStreams.exe downloading and writing out the files after each reboot.
What the heck is going on here? How can it be this broken? This seems to have started about 1 month ago (maybe when Photo Streams where removed?). But this isn't photo streams - this is Shared Albums.
