Addon price is not updated for old subscribed users when we update the addon price.

Hello,

I am using Payplans, and added Addons to a recurring plan.

So when user pays for a subscription and selected the addon lets say addon price is $10, so on every recurring payment, it charges user plan price+addon price.

But lets say i changed the addon price, but then also the user who already has subscription is charged the old price.

I want if we change the addon price, then new price should be charged.

Please help with this
