GPU Particles on IOS iOs 9.3.5

HI Epic and Community,
im having problems with GPU particles in UE4 4.12 deploying on IOS
Im using a Ipad pro 9.7" that is a A9, i bought this hardware after reading this page that a8+ devices where supported for GPU particle effects.
However- they do not render at all when testing on the device but do come up in mobile PIE.

I think it may have something to do with this issue.

But unsure.

I have tried every GPU particle effect in the content examples project as well as a fresh particle with the only modification being its type data to gpu sprite.

Please advise, thank you.

Specs:
Ipad Pro 9.7"
OSX 10.11.6,
Xcode 7.3.1,
UE4 12.4.5 - (binary release)
building to iOs 9.3.5

Hi,

This is a regression, we noticed to late that GPU particles were accidentally disabled for iOS, it will be fixed in 4.13.1 (UE-34782).
