A:AnswerGreat questions! Yes, you can add to your app and manage multiple devices under one account. You can play separate music on each device with the family subscription that allows multiple accounts to cater to individual taste. They can also be linked together to become a whole home stereo and surround system. Also a great way to drop in from the app to page them for dinner since it can function as intercom as well.
A:AnswerIt is primarily an Amazon Alexa device but does function as Bluetooth speaker. Simply as Alexa to enter pairing mode or to find nearby devices and connect that way or via the Alexa app. You can enable skills to link nearly any streaming service as well.
A:AnswerIt is not the same. I tried using it in The Dominican Republic. Once I told it to play music it played on my devices at home in the United states, lol. It could be different for you but mine did not.
A:AnswerI don't know but often have the same question. Generally if you wait a moment and try again, it will work. Best possible answer? Alexa is female! :)
