For as long as Apple Music has been around, the streaming service offered first-time subscribers three months of free use. But it looks like that has changed. The company quietly shortened the free trial period to a month. We've checked the Canadian portal, and it already states that "One month free, then $9.99/month."
There don't seem to be any pricing changes yet. So, if you're already a subscriber, you don't have to worry about paying extra. If you're trying out the service for the first time, unfortunately, you don't have as much time to enjoy the features for free until you have to pay.
