The reason that I always publish to Google Play/Android first, is that the updates are almost instant and always available the same day. All the other platforms take longer, between 1-7 days. Even longer if the update gets rejected for something silly.
This last update to Train Sim was especially important because of the major improvement to sound effects, so I wanted to publish these changes ASAP. I am happy to announce that this new version of Train Sim with improved sounds is now available for iOS, Amazon Store & Windows Store. The only remaining platform I still have to update is Windows Phone. However Windows Phone affects a very small % of the player base so at this point over 99% of Train Sim fans have access to the newest version.
