When Amazon Music Unlimited was rolled out, it was free on one Echo device. You had to select the specific device you wanted to use it on.
It seems that is no longer the case, but it is very hard to get information. Despite that I never subscribed, my account shows that "On April 25, 2017, your Unlimited for Echo subscription was canceled. You can subscribe again at any time." Maybe that was when Amazon discontinued providing it for free on one device.
Right Meya, sometimes my memory is less than perfect, but my very specific recollection is that when it rolled out, Amazon alerted Echo owners that they could use it with one device. This was late November 2016. Maybe that WAS a 'free trial'. But since you can use it with multiple devices (each at $3.99 month per device), why would Amazon tell us to link it specifically to one device? I recall that very clearly, and that I was NOT signing up for a 'free trial'. And if it was a 'free trial', why does my account show the service ended in April 2017, which was 5 months after it was rolled out and initiated on my Echo?
You are right, I need to contact CS and actually was starting to do that a minute ago. Thanks for trying to help!!!
I don't know why Yousuf in CS thought to say that.. but that is incorrect. It was never free for Echo users beyond the standard 30-day trial. It was always $3.99 for one (and only one, to add another device you upgrade to the reg plan) Echo device with a 30 day trial right from the day it started.
