Is this the same Portal device that they disabled every feature on other than Messenger and WhatsApp calls that I can now only use as a bluetooth speaker?

Yep and the speaker is not half bad! It has good hardware. Its a shame they could not spin it off to anyone else(not for lack of trying) before they were "forced" to kill it because, basically, meta's stock was at 90$ at the end of 2022 and everyone was just spewing a derivative of the statement: "Focus on extremely short term profitability else your(heavily) stock compensated employees will all leave."

The same portal device that is running an EOL version of Android and isn't getting security updates so you probably want to keep it safely isolated from anything important (if you weren't suitably paranoid already)

Now you can install a Spotify app and use it as a standalone speaker?
