App Library flakiness

I'm trying to figure out if the app library is really as flaky as it seems or if I'm simply doing something wrong.  Many times, I will bring up the app library, and my title simply won't be there, even though it's installed.  Just now, I saw it there, then I used the three-dot menu to get to "settings" and checked that I have the correct release channel selected, and then when I returned to the App Library, I watched it refresh and my app was gone.  So were a bunch of other apps.  The "all" category showed 24 items, and the "installed" category showed 25.  I rebooted my headset, and the all category now had 35 items, with 34 in the "installed" category, and my title was again visible.

Another question is how I force my title to update when I change the release channel.  I swear I saw an "update" button on the main title details screen that I used before, but this seems to be missing now, and no matter what I do, I can't get it to update, despite the HMD telling me that I have a different build code installed than the one that's available in the selected channel.  I've tried changing the release channel and changing it back, and I've tried rebooting.  Is there a way to force this?
