Family account, but me and my husband can’t play music at the same time.

[#1]

We now have an account each, but we can not listen at the some time. We have family plan.

Hey there!

Please make sure you're logged into your separate accounts, as different accounts cannot interfere with their separate playbacks.
You can view the email address you're logged in with by opening your app Settings.
