Echo Acting like an 80s robot that is misfiring
My Echo is out of warrantee and recently she has been very strange. She frequently doesn't respond to my voice commands and then shuts down and/or says she lost internet connection, which is fine with other devices. Could it be steam from shower (which is low as I keep door open in bathroom when shower is being used) or something else? She is acting like a misfiring robot from an 80s sitcom at times. I'm not sure what to do?
