Unable to cancel Apple Music subscription

When I try to cancel the subscription, it doesn’t work. I go to the correct screen, which shows the subscription options. I currently have Individual (1 Month). Below there is the red “Cancel Subscription” button. I tap that, and then the only thing that happens is the text for the subscription options becomes light gray and the “Cancel Subscription” text becomes light red. I know there should be a little window that pops up asking me to confirm whether I want to cancel. There is no such window. I can’t do anything else after this.
