Digital subscriptions start with the next issue to be posted, NOT the current issue.
The digital subscription app will not recognize your login details until the date that the first issue in your subscription is posted.
The digital issue posting dates are located here: https://shop.strategyandtacticspress.com/SearchResults.asp?Cat=59
The digital subscription is downloaded from an app that is found ONLY in the Apple App Store (Android app is currently in development). There is an app for each publication, so if you get a subscription to Modern War, you need to download Modern War, not the World at War or the Strategy & Tactics apps.
The Strategy & Tactics App: Strategy & Tactics Magazine App
The World at War App: World at War Magazine App
The Modern War App: Modern War Magazine App
