Virtual joysticks zOrder

Hi,

I’m using Virtual joysticks on an Ipad package, where the ipad is used as a companion to a PC application.
The Ipad contains a navigable map and the virtual joysticksare used to control a character on the PC Side.

Whatever the zOrder I put them in (Virtual Joysticks are engine hardcoded rendered at -11), they will always be behind my UMG elements. The should be in front. If the map is disabled i can use them just fine…

Who can point me to rendering your virtual joysticks in FRONT of everything?

Many thanks,

UPDATE:
Decided to implement my own Joysticks in UMG. So this problem has not yet been fixed.
