Alexa Media Player Issues

I hate asking for help with what may be a simple issue, but I have spent HOURS trying to get my Echo Studio to show up in HA as a media player. Nothing is working. I’ve deleted and re-installed numerous times, restarted HA between steps, and have tried solutions even from old posts. I’m missing something stupid, I fear… I also signed up for the cloud option, so I’m in my 1 month trial. Are there known issues with installing this integration via HACS and configuring it, lately? I can never get past the authentication part without an error. I have re-dome the Amazon 2FA setup multiple times and it all looks okay on that side, as far as I can tell.
