NOTE: The Extended Pack performs unpredictably on certain devices, including those made by Huawei, OnePlus and Blackview. This is due to their proprietary operating software. The pack may not download, or the app crashes and your phone reboots. In either of these cases you can contact firstname.lastname@example.org with the order number of your purchase to be refunded.
