Hey guys posting this thread because looking for a quick response other than Reddit. So we have 3 echo dot 3rd gen. My Amazon account is Prime. I have just subscribed to Amazon Music Unlimited HD family plan which is currently £7.99 for a time and the £14.99 after trial period. My mums Alexa echo dot is signed in to her non prime account. For instance when i ask "Alexa, play Children by Robert Miles" she tells me to sign up for £3.99 a mth. Soo what is Amazon household if i can't give my mum access to my prime music subscription on my account ?
