Echo show/camera help

We purchased two Echo Show 5 devices during Black Friday sale. We love them. We have them connected to our cameras inside for our twins.

Just recently our Echo’s have decided to stop showing us on each of Echo’s the same camera at the same time.

we’ve reset both Echo’s and the camera.

but now we can’t watch/view the same camera on both of our Echo’s when before we could.

are we missing something to do to fix this?

or are we just stuck not being able to view the same camera of on both of Echo’s at the same time anymore?
