This appears to be very intermittent.
Yesterday afternoon, when they said it was fixed, I tested, and it worked most of the time, but once didn't call install.
This
morning, I inspected my logs, and it appears someone else actually
installed my application, and then removed it, but I only saw the
remove call.
Maybe this is good news that someone is actually
testing our apps? But it's bad news that we have no way to keep track
of installs.
