Valve announced earlier in the month that a streaming app for Steam would be coming to Android and iOS. While the Android version launched in beta as planned, the app never landed on Apple devices. Turns out, Apple has refused classification for the app, stating, "there were conflicts with app guidelines that had allegedly not been realized by the original review team."
A press release from Doug Lombardi, Valve's VP of marketing, reads, "Valve appealed, explaining the Steam Link app simply functions as a LAN-based remote desktop similar to numerous remote desktop applications already available on the App Store. Ultimately, that appeal was denied leaving the Steam Link app for iOS blocked from release." Valve is hopeful that Apple will reconsider its decision.
