UGH! I wish I waited to 'test' this Apple One, versus me rushing to sign up when I did.i just spoke to apple about this and pretty much what happens is, it cancels out. once you bundle you'll get the first month free and after that month you'll be billed monthly. so if you're not in a hurry to bundle anything i'd wait it out. my free appletv+ sub ends 2/21/2021 but ill be subscribing to the premier plan mid Nov. 11/15 is when the plan ends for my monthly music and storage subscriptions.
If I cancel the free trial now, I lose my Apple TV+ that I had till Feb 2021.
