UI Button not sending event on IOS build only

We finished our game recently but we haven’t been able to publish on the app store because of this small but important bug. The play button we use for moving from our scene menu to our scene game is working both in the editor and on android but not on IOS.

We already tried removing the event system and recreating it without success and we trie replacing the button script by a toggle.

It turns out my issue was caused by a bug in IL2CPP on iOS (I switched to this from Mono recently). Calling SendMessage() for buttons won’t work on iOS.
