Hi
Please temporarily uninstall the Amazon shopping App and retry. Once your Sonos and Amazon accounts are linked, you can reinstall the Amazon shopping App
Okay thanks for confirming, that fixes most occurrences of this issue and sorry for missing that you said that you had already tried that. ♂️ . Can you check your location is correct within your profile on www.sonos.com
Can you confirm which country you are located in? Do you have any other Sonos devices working with Alexa?
sorry my mistake, I must have done it wrong the first time, I got it to work this time
