unity 5.4 scroll view problem

Such as topic, I found a bug. It likely a scrollview in PC mask no problem. But packaged out Android mask is not working. so I think it will be 5.4 bugs.Can anyone under test, now I don’t know what problem on my side

Hi, I had the same problem, and at the beginning, I cound’t fix it by changing to RectMask. But, after expending a while trying to find out why this is happening, I found out that if it is created the ScrollView and then Mask is changed to RectMask before building the game, elenzil’s solution works magically. I am not 100% sure of what i’ve found out, this is what happened to me though.

Unity 5.3.5f1, Android 4.4 kitkat
