I have a found a curious behavior recently. I was looking for xbox music and the pinned tile was missing. I went to the Windows store and re-downloaded Music app. It said downloading then installed. When I went to look for it in the list of apps, it was nowhere to be found, nor anywhere when I use the search tool. I cant seems to play my music because I don't have a music app. This is curious, anyone seeing this behavior?

I simply turned my phone off and on when this happened to me. Solved it for me, also try using Cortana to open it.

I should clarify, this happens on my Nokia 2520 Tablet.

I tried to switch off and then back on. I even downloaded XBOX Music app from store again. Once downloaded, I opened it from the message notice at the top. Closed XBOX music app. Tried to reopen by looking for it. Nowhere. Not even listed in apps list of "apps by date installed" filter. I'm at a point where I may just reset to factory.

Have you tried using the search? Sometimes they way apps are arranged in the All Apps area is odd.

Well backing your phone up and resetting could work since my Cortana wouldn't say a word and would look everything up such as do an impression but resetting solved it. But you could also call support they might have an idea

Something similar happened to me using the Dell Venue 8 Pro.

Most of the MSN apps were saying they were in need of repair.
Each app when I tried to open said visit the store to repair.

There seemed to be no option do this repair.
I restarted the tab and found all the apps gone.

When attempting to reinstall all apps said installed yet weren't to be found anywhere.
A manufacturer update popped up in the taskbar so I battled thru that.

After a couple of more updates\restarts the apps installed themselves and showed up.

Another weird thing is in my store settings I found an account had been added from my RT recently sold.
Strange because I wiped the RT back to factory and removed it and any back-ups from my MS account.
I probably missed something and the new owners account was linked with mine.

Well I ended up backing up and resetting. All my missing apps reappeared. Of course, the wake from sleep mode bug reappeared, which I had to fix. Seems okay now.

I've suddenly got the same issue. Appeared when my hard drive suddenly became 100% full thanks to downloaded updates etc.
Strange thing is, a few apps will reinstall eg. Trip Advisor. Most will not. I've now got to 5.7GB free, but still can't do a re-fresh. Message says I need 1.6GB more free space to do refresh. Help! I'm a little stuck here.

Update - now I see the problem only impacts apps previously installed - and only some of them. New apps can install OK. Any ideas anyone?
