Hi All. I have an Echo dot in my kitchen and an Echo tower on the other side of my house in a bedroom. In the last two weeks a strange behavior has started. If I'm in the kitchen and say, "Alexa, set a timer for 10 minutes," I receive no response, but 10 minutes later the tower in the bedroom plays the timer alarm. If I'm in the kitchen and I say, "Alexa, play X (music)," music plays in the bedroom. It doesn't happen for every command: Flash Briefing works. "What time is it?," works. I'm stumped. Any ideas? I've reset both devices, but no change.
