As part of the process when setting up your Apple Accounts together with Loialcard, there is a yearly payment.
You (the account holder) may opt-in for automatic membership renewal at account creation (preferred) or later at any time by toggling the Auto-renew option in the Membership details section.
If you have opt-int for the automatic membership renewal then Apple will charge your default payment method on your membership expiration date. If no credit card has been added you are prompted to do so as per this example.
An expired Apple Developer Program membership will have the published apps automatically deactivated from App Store by Apple, so your users can no longer find and download the app. Also, Loialcard can't then update the apps and even though Loialcard has admin rights to your account, managing the payment is unfortunately outside of our access.
Apple will remind you prior to your annual membership to Apple Developer Program expiring on the e-mail address associated with the account holder. Loialcard will also help you remember this if you haven't opted-in for auto-renew.
If you have opted in for auto-renewal you will receive an email as per this image two weeks before the new period and then you are all good and will not experience any interruptions.
If you want to opt-in for auto-renew or if the payment method needs to be updated, below is a step-by-step guide on how to.
Since the Google Developer Account only collects a one time payment upon account creation, this issue does not apply to your app on Google Play.
Steps to update Payment Method and verifying auto-renewal.
If you have received an email from Apple about payment method needing to be updated, follow the link in the email.
The information about missing Payment Method can also be found in alerts inside of the Apple Developer Account panel.
Or otherwise simply go to the web address of your personal Apple ID account:
https://account.apple.com/Log in to your personal account with your Apple ID (using the email address as per the email).
Go to Payment and Shipping to edit or add payment method
Now navigate to your Apple Developer Account:
https://developer.apple.com/account
You will find your current membership expiration date in the section Membership details.
Scroll down to the section on Membership details and activate the Auto-renew toggle.
Here you also find details about your membership such as the Team ID, type of membership, who the current account holder is, and the membership expiration date by the label Renewal date. Your membership will expire past this date unless you renew your membership before the date, or opt-in for automatic membership renewal.
Please note that it may take up to two weeks from the date of the payment is made until the new renewal date is actually reflected in the account.
