^Exactly this.
Marley, this has nothing to do with the doorbell WiFi connection or any other standard troubleshooting step, this is a bug on all Amazon Fire 4k sticks. Namely, Ring simply will not work with an echo device unless you wake up the remote first.
It’s a bug identified by the community that needs fixing. But alas, I have also given up on this functionality as it hasn’t been working for so long. ?
