Experience a similar error when testing my app recorder.

I am trying to add a "share" ability via the content-hub. I get to the
point when the peer picker window is displayed after which there is a
failed event.

On checking my app logs I find:

  This is printed to the application's log about once every other second and makes it hard to read the application's own debug output. For a better app developer experience this message should be silenced.
