How do I cancel my Mario Kart Tour subscription?

To cancel a Mario Kart Tour subscription, one needs to manage their subscription from within their device's respective app store. If the subscription was made through an Apple device, it can be cancelled by going to the Settings app, tapping on one’s Apple ID profile at the top, selecting 'Subscriptions,' locating Mario Kart Tour in the list, and then choosing 'Cancel Subscription.' For Android devices, one would open the Google Play Store app, tap on the three-line menu icon to access Subscriptions, find Mario Kart Tour in the list, and then select 'Cancel Subscription.' It is important to note that after cancelling, the subscription will remain active until the end of the current billing period.
