Hello, good evening, I'm from Colombia and I have the same problem... I already have the skill installed on Amazon Alexa... but when I try to link the era 300 with my Amazon account it doesn't load and tells me to try again later... Help please

Exactly the same, any tips/links how to resolve?

> Every time I select 'connect to amazon', it just spins and spins and never loads the next page! 

Tried 4-5 times now, waited several minutes, eventually getting:

“Leider ist beim Hinzufügen von Alexa ein Problem aufgetreten” (=”a problem turned up”)

Hi All

Have resolved the issue with Sonos tech supports help.

The problem appears to be related to certain Andriod devices. You shouldn't have this issue with iPhone. My mobile is a Samsung S23 Ultra. I re tried the log in process by downloading the Sonos app to my sons Oppo handset and it added Alexa first try!

Hope that this helps

Thanks! I used a Samsung (S21) too. Managed to set up the Era 300 from the Alexa app side and might still experiment a bit later. For now I am anxious not to mix in too many setups, with the current Sonos sw issues you hear about I want to keep everything simple for the moment.
