I went to cancel my Adobe Stock subscription today, exactly 1 month after signing up (signed up on the 2/14 and it is now 3/14). It looks like I was invoiced today, so apparently the rules are that once invoiced I am stuck with the plan. Is that right? If so, that sucks. I get it if I came back on 1 month + 1 day, but this seems to be a gray area that should benefit the subscriber.
Cancellation would need to be done before the renewal date - before 14th of March in this case.
I will arrange for the subscription to be cancelled and refund the March charge.
