This morning, I saved a text file (*.txt) on my desktop for later reference. I can see and preview it. But, later, as I am attempting to attach this file via a website modal, the Finder pop-up cannot see the file -- not with sorting, or even typing by name. The permissions are correct.
The file is correctly sorted in my Documents stack. The desktop is saved to iCloud, so this should he universally available, but it originated here on my Macbook, so it should still be available.
This doesn't make sense to me, so I wonder if someone can explain what the issue is.
