Render Target painting not working on IOS

I’m trying to implement a painting game using render target and canvas painting. It works ok on SM5 but on Ios doesn’t work and the scene doesn’t load. If i activate use metal desktop the game crashes on Iphone 6.
I have mobile HDR enabled. If i use a SceneCapture camera it works fine but "**Begin ***Draw Canvas" *looks like its not working on mobile.

Any solution for this?

I just discover that it works but only if i don’t create a render target texture in runtime.

I got the same problem and I really need to create RT at runtime,do you have any sulotion for this?

And I found even if I use a static Canvas Render Target ,the canvas still not working on my iphonex.
