On ios the keyboard is always shown over the popup, so sometimes you can’t see your input. We’re using com.ionic.keyboard plugin. Someone has a similar problem? Can’t find a solution here in forum. Looking forward to a reply.
To answer my own question is similar to this answer
Use
cordova.plugins.Keyboard.disableScroll(false);
when the popup open and usecordova.plugins.Keyboard.disableScroll(true);
when it close
that way page contents appears below the statusbar
