I am new to Ring and had the Pro installed about a month ago. Also have had the Wi-Fi extender installed. I had Amazon come out to install and the a second time to trouble shoot. The audio cuts in and out and is delayed. The notification of someone at the door is delayed by 20-30 seconds. The Amazon installer said this is all because there are so many Ring doorbells in our neighborhood. I am disabled and not very tech savvy.
