All supervisors are informed with a spreadsheet when new devices and updates are coming. He probably just didn't open it up when it was sent to him.
They get notified of training when new devices and yes when new updates come out and to expect customers to answer questions.
Even if you own the phone they don't want the hassle of doing an exchange. That has been my experience. It could be the area I live in that they just don't want to be bothered with dealing with an existing customer sale with stores always being jammed packed.
Their screens will never show something coming soon. Ever. They release it when exact dates are on it. Just like they don't want their sales guys to know a new phone is coming a week later.
Move the products on the floor. Have you ever heard a rep say wait until next week when the xyz device comes out? Never. If they do, ask where they heard it and they will mention on the web.
I am not trying to be rude or argumentative, just a healthy debate.
It could also be because of the early confusion of if updates would be coming from Google or Verizon, which we now know is Google.
By me stores are becoming fewer and Kiosks are the norm, which is now starting to revert back to full stores. That could be an issue onto itself.
I am sure the bug is known, but a fix I don't think is coming, at least anytime soon.
