Changes in Bluetooth protocols in MacOS, ChromeBooks, and Windows have made the Classroom Communicator incompatible. As a result it has been discontinued, and is no longer supported.
Multiple Evos Bluetooth pairing, updating, and renaming is available through the Evo by Ozobot app iOS and Android (if you can't find multi-bot update or multi-bot rename, you may need to update the Evo app on your device).
