If you have a recurring subscription, like YouTube Premium or a gaming membership, changing the main payment method should update it automatically. But double-check! Go back to “Subscriptions” in the same menu.
Tap on any subscription and see which method it’s using. Sometimes, subscriptions hang onto the old card like a stubborn ex. You can change the method directly from the subscription page if needed.
I once had a music subscription fail because I forgot to update it. My playlist went silent mid-run. Don’t be like me—check your subscriptions every few months.
