Text field disappear in some situations

[andyleekp]

I found that there is a problem in mobile environment.

In some kind of situations such as sliding the task/navigation bar or switching other apps and go back my app again on Andriod or iOS, all the text fields in the input fields which attached with the script of "Native Edit Box" has gone. But when I reload the scene or set the game object to inactive and active again, the text fields appears again!

Is there any missing thing in the script or we can do so that to fix this problem? I think the text fields actually are still here but just go somewhere, may be out of camera or something? Thanks for attention~
