Unreal 4.26 Mobile AO

Hi,
I tried to get the GTAO to work on my Mobile Device(SM-T830)… I enabled “Mobile AO”. I set the “Mobile AO Quality” in Scalability.ini to 1. I set “HDR for Mobile”
I can see the AO with the Android and the Vulkan Preview in Unreal.
I launched from Unreal with ES 3.1. BUT no AO on Device. I builded with ES 3.1 and Vulkan BUT No AO on Device. What did I wrong?

In my Scene I have “ReflectionCapture” “DirectionalLight-Moveable- no shadows” and a “Skylight - Moveable”

Is there anything about the SDK Version?

Is there anyone who gets this to run?

I installed SDK with Codeworks and have no Errors in building.

If Im right, the GTAO works over the normal “Postprocessing Volume”, because, when I enable Mobile AO, The enabled Postprocessing AO is the only way I see it - also in the Android Preview in Unreal.

Please Help, there is no more setting i dont testet.

thanks

Ok. its working now. For me only with Vulkan.The Problem was my Device.
