My Question or Issue

I'm a subscriber to Premium and recently bought my daughter an Amazon Echo with Alexa. She wants to be able to listen to her own music often at the same time as I'm listening to my own music.

So, I upgraded to Duo, but I can't work out how to allow my daughter to listen using one account via Alexa, while I still have access to the other on my phone, at the same time.

She's a child so doesn't have her own phone or amazon account etc so how do I do it? Since upgrading to Duo I can see that I can 'invite someone' but how do I do that when the person I want to invite doesn't have their own device, other than an Amazon Echo?

Thanks
