Subscription Rebill

Apple is always trying to take the money out of my account when I still have 1.5 weeks left of my subscription. It will tell me “update payment details” what feels like every 2-3 weeks when I’m paying for a monthly subscription. Why do I constantly get bothered with notifications about my payment details when there’s still over a week left of my last payment? A couple days before I could understand but a week and a half is ridiculous
