A month ago I called the support line. They told me they can no longer do "manual" upgrade tries and if you don't get an upgrade with the automated system, there is nothing further they can do and they can't see R space themselves.

I don't know if this is true, or if they misunderstood my question, or I misunderstood their answer. But my understanding is they can no longer send it to a "RU team" to check over for space.
