How do I get the updated app? The Microsoft Store will automatically update affected customers. Alternatively, customers can get the update immediately; see here for information about the apps installed on your device. It is possible for customers to disable automatic updates for the Microsoft Store. The Microsoft Store will not automatically install this update for those customers. If you want to get updates immediately, or if you don't have automatic updates enabled, select Get Updates. You can then update apps individually by selecting Update for each app, or you can select Update all to install all updates. We recommend that you select Update all as a best practice to stay protected.
