Hi there,
I thought I'd make a little list of Construct 2 expressions, conditions and actions that do not work on certain devices and/or browsers. I don't know if such a list has already been started before, but if so tell me and please excuse me.
Feel free to add to this list but make sure you test the expression, condition or action you have issues with on several devices and browsers before posting.
* Firefox / Seamonkey (Mozilla) don't detect the value of the "loadingprogress" expression until it's reached 1. They do detect it when its value is 1 though. (tested with Firefox 39.0 and SeaMonkey 2.33.1 on Windows 7)
* Safari on iOS 6 (and maybe other versions of Safari and iOS) don't detect audio object's conditions "Is any playing" nor "On ended". It does detect "All preload complete" though. (tested on an iPhone 4)
