I received the Chime Pro 3 days ago and have tried several times to get it set up. Finally called support and the tech did a great job of walking me through steps that are NOT part of the instructions…anywhere. After hanging up with the tech, I moved ahead to select the chime tone…NOPE. There are three sounds to set in that section, two of which worked but not the chime tone so I couldn’t proceed. When I tried to start over, it was offline. I’m not a tech newbie and can attest that the setup procedures for Chime Pro are poorly written and far too difficult for the typical purchaser. I’m not spending any more time trying to make this work and will be shipping it back to Amazon for a refund.
