I have a default joystick on the left of the screen and I made a UMG button to excute some events.But the strange thing is that if I first move the joystick(do not release))and then tap the UMG Button,the events never get fired for the first click,but if I click on the button again,that works.I have tested this issue both in the mobile previewer and on my iphone6 plus.If you have any advice concerning this,please let me know.Thanks very much!
After I change the button event trigger to OnPressed,everything is OK
