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 World at War, you need to download World at War, not the Strategy & Tactics app.
The Strategy & Tactics App: Strategy & Tactics Magazine App
The World at War App: World at War Magazine App
