Spotify stopped connecting to Echo. As of yesterday, Spotify won't connect to my Echo. I had been connected earlier in the day, and hadn't changed anything. Spotify shows the Echo as an available device, but when I select it, it says, "Connecting" for a minute or so, and then reverts back to saying, "Available devices". If I ask Alexa to play XYZ, it says, "Playing XYZ from Spotify", but doesn't do it. Obviously the Echo perceives a connection. I've checked the status of my Spotify Premium account, and it's fine. I disconnected and reconfigured my Spotify account and my Amazon Alexa account, but it didn't help.
It happened again today, and again I had to remove and reinstall the Alexa app. Still, it seems to be a Spotify problem, because Alexa sees Spotify, but Spotify doesn't see the Echo. Also, the Echo was connecting to other Smart Home devices.
