Thank you for reporting this, we have investigating and only the scenes are affected. We’ve added this in the backlog to be fixed.
I’ll get back with updates when it gets fixed.
Yes, I am seeing the same for Alexa. I replaced a power plug, but could not move the name from the old to the new. I had to pick a different name. However, after a week I removed the old name from the Alexa app list of devices and then it seems to work.
So it looks that a changes is a two/three step thing, just like adding one.
