Hi folks. Newbie here to all things HA. I was super excited to configure my Raspberry Pi5 and install Home Assistant on it and have a bit of a play. One of the challenages that I am facing now is why I’m unable to add my Alexa device to HA. I’ve followed the steps a zillion times and tried the suggestions offered on Google Search and Copilot without any success. No matter what I do, I cannot get passed this authentifcaiton issue. I’m able to log into my Amazon account using the OTP from the Authentication app so I don’t believe there’s anything wrong with my account as such. I’m based in Melbourne (AUS) and from what I can tell, my regional settings are all correct. I log in via the .com.au domain. Would love to hear from other who have had similar issues and what tips/tricks there are to getting past this issue. Thanks all 
Same issue here. Just logged in via the Alexa Media Player so this is not an issue with my account, password, etc. With Alexa Media Player you need use the 2SV 52-char code generated but this is not the case here.
At a loss with this, any help appreciated!
