Forgive me if this has been answered elsewhere, I did a search....
This past weekend, I opened the "Apps" app, and I had a constantly moving progress bar that says, "Syncing metadata." Hours later, it was still there in all of my profiles. I rebooted, signed in/out, etc. but nothing fixed it. About 36 hours later, it was gone.
Then yesterday, it happened again. It's been about 24 hours later, and no change.
Any clue what's happening?
