IOS keyboard attach ion footer and input disappear when keyboard is visible

Hi,
I'm using keyboard in a modal on an input in ion-footer with keyboard-attach on,
it's working fine in android,
but in IOS when focus is on input, keyboard appears and Footer disappears,
it's doing so in emulator and real device,
using ispect element, I can see the ion-footer "space" when I hover on the element in the inspect element tool (if you get what I mean) but nothing actually is visible, but it's in place just over the keyboard but invisible.
any Clues?
