Steps to Upgrade
Therefore, if you want to upgrade we recommend you go the in-app purchase route since it is incredibly easy. Tap "Upgrade" from the TrailMix dashboard, then tap "Buy Now" to begin the process. After that, enter your password or touch ID if necessary. You will see the current price and can confirm that you still want to buy before completing the purchase.
After upgrading, you can share the upgrade with your other devices via the Restore Purchase option. This option also comes in handy if you need to reinstall the app.
