BlackBogey:So when is an update "not mandatory"? I play on PC and don't really ever see an option to decline the update whenever it pops up (if I want to continue to the game anyway). Is what you are saying Sam, is that it is possible that someone on IOS hasn't been forced to take the update that was out 3 days ago?
On PC, if you launch the game directly by starting golf.exe (not launcher.exe), it will not check to see if there is an updated version of the game. You can continue to play on the version you have. You will only get the latest version of the game if you launch the game via launcher.exe. I am not sure if the PC app (golf.exe) forces you to update eventually or not.
On Steam, you will see an UPDATE NOW button instead of a PLAY button. So you won't be able to play on Steam until you update.
On Android, you can continue to use your current version of the app until the update is marked mandatory (I think in the Google Play store). At that point, you'll get an Update splash screen in the app which will force you to go to the Google Play store and update the app.
I am not sure how it works on iOS or MacOS.
