"Missing" Discovery Go App

When I ask for "Discovery Go", I see the words print but it comes back with "the app is not found".  Discovery Plus still works fine.  This just started several days ago.   It is also not under Popular Apps, where it has always been before.  Again the Discovery Plus app is still there.  I have been using the GO app for years.  I contacted Support by online chat. 

After trying a few things, they had me turn off the Flex box for an hour while they reloaded the software and re synced with the mainframe.  They contacted me by text message after an hour and, when I indicated that the problem was still there, I was connected to an Agent.  After trying a few things, the agent had me exchange the Flex box with a new box.

The new box works the same as the old box (with a few nice added features).  I did some further checking on my own and found the app under All Apps.  The app works fine but to use it, I have to go to "All Apps" and use 35 down selections.  Would you get the audible search to find it again or move it up to Popular Apps?

As an unrelated item - could you add the "Philo" app?  I can access it though my computer or thru Roku but there is no app in Flex.
