Alexa Repeats Alerts on Echo

I have a Ring Door View in the U.K. and 2 Amazon Echos.
Just recently I’ve noticed that when I have motion at the front door, Alexa tells me, and then tells me again straight away.

Has anyone else experienced this?
Factory reset of the Echo’s and the Ring doesn’t help.

Thanks

Hey @LB79. Is the alert coming through on the same Amazon Echo show twice, or does it go to one show, and then to the other to alert you? Could you capture a video of what this double notification looks like from the Show?
