I can’t be top up in game

magar66,

Are you having trouble with an in-app purchase? (See Buy additional app features with in-app purchases and subscriptions for information about in-app purchases.) If so, depending on what happens when you try, check out the following:

If you are able to make a purchase, but can't find it, follow If you can't find or use your in-app purchases.

If you are unable to make in-app payments:Check Settings > Screen Time > Content & Privacy Restriction. If on, continue to iTunes & App Store Purchases > In-app Purchases and set to Allow - Prevent in-app purchases from the App Store.Check your payment information for your Apple ID in Settings > [Your Name] > Payment & Shipping. - Change, add, or remove Apple ID payment methods.

Hope this helps,

Have a good day.
