Lightroom doesn't see photos in folder to import

I have a folder called "icloud" that my icloud syncs all my iphone photos. Periodically, I sync this folder to see/edit them in Lightroom. I haven't done this for some time, but now when I try to sync the folder, it says there are no new photos to sync. In Windows explorer, I can see there are thousands of jpegs to import. I've also tried importing, copying, adding, as well as dropping files into the import window. I've changed import folders, checked/unchecked avoid duplicates, etc... All apps are updated. Any ideas?
