I have renamed my Echo (Dots) & since then Alexa cannot play Spotify anymore. I have restarted the phone, reinstalled the spotify app, deleted and re-added the access rights for Alexa in my account and even named one of them back - it remains impossible. The Echo (dots) are not listed as possible devices on neither app nor desktop computer &if I try to tell Alexa to play spotify she says okay but never starts (same if via Alexa App). Additionally, I cannot delete the Echo (Dots) with the old names that are still listed (grey) on app and PC as they only read "currently unavailable" and it's impossible to click on, three dots on the side are also not shown (if I could upload a screenshot I would). Is there anyone who could possibly help me?
