My humble opinion is that the device connecting to the doorbell has nothing to do with the transmission device.
Since Amazon now owns Ring, and the Amazon flagship product is Alexa, Ring should not have volume issues with Alexa, period.
Once the problem is solved with Alexa, the other Android and Apple products will be solved.
If Ring cannot work with the Amazon Echo, there is a serious problem.
The problem is not going away, it will only exacerbate as time goes on with no solution. This should be a top priority for Ring and Amazon before this ends up in the media.
So from reading this forum, what I get is that the company did nothing to fix this problem. Everyone is having the same issue and so does the person I'm writing this for. For the people that submitted their videos (which I don't see the point for the company to have, the problem is with the hardware) were your devices fixed? Can the person on the outside hear you?
For a device that is so much money it's dissapointing garbage.
