The billing owner can manage a web subscription’s card and invoices in Settings → Billing. Other household members may see the status without edit controls.
Why are there no invoices?
Check whether a payment has completed and whether this is a web subscription. Apple provides receipts for App Store purchases; those payments won’t appear in Vylo’s web invoice list.
What if I just want to cancel?
Use Cancel your subscription. Removing a card and updating a card are different actions; the confirmation explains any effect on renewal.
Payment details belong in the secure payment form. Don’t email a card number or security code.
