This is still a relevant answer if you mean:

  • How do I change from one subscription plan to another?


It is very convenient to change the subscription plan from weekly to monthly or yearly or vice versa. You can follow the instructions from Apple.


Apple handles the effect of such changes. When you change the plan, the 'change' will be effective as per your new preferred frequency after completing the existing cycle. That is, if your existing plan is monthly and 9 days are still remaining for the subscription to renew and you switch to the yearly plan, the yearly plan will be in effect when the current subscription month completes - after 9 days.

In other words, the change in plan will not happen immediately, if there are still a few days remaining for the existing subscription cycle to complete. In such a situation, after those remaining days are passed, the new subscription cycle will be in effect.
