Since your app store processes all purchases made for Sideline, we do not have the ability to edit or manage your payment options on your behalf. If you would like to edit the form of payment for your Sideline subscription, follow the steps below as provided by Google:
By default the same payment method you used to purchase the subscription will be charged for renewals. Renewals may take place 24 hours before each subscription period starts. To change the payment method used:
- Open the Google Play Store
- Tap Menu AccountSubscriptions.
- Find the subscription you want to update.
- Tap Update.
If your payment method is declined or has insufficient funds, your subscription may be cancelled. If this happens, set up your subscription again.
For reference, please see: https://support.google.com/googleplay/answer/7018481
If you are having trouble subscribing to the monthly or annual Sideline subscription or having trouble completing a payment in the app store, please refer to our Service Status Page first to check if there are any current purchase disruptions with your app store.
If you have any further questions about your subscription, please feel free to reach out to our Support team and we'll be sure to help!
