Pretty sure I already know the answer. I have 3 dots and an Echo, all bought in Canada and registered my amazon.ca Prime account. This does give me "free" access to Prime Music, which we do use. I also have a basic US Amazon.com account. I'm guessing that if I try to switch the Echos to that account I will lose Prime music. Correct? It's a tough decision since some of the US skills would be useful BUT I would also lose some Canadian skills, News and Weather would not work as well. Has anybody actually switched 9not just set up as US from the beginning and has there been a downside? I know lots has been written about this but I'm still not sure what I should do.
