Shaders and Trail Renderer don't work on Mobile using Qualcomm Vuforia Plug-in.

Hello.

I am making a mobile app using the Qualcomm Vuforia Plug-in and I am trying to make use of the trail renderer and shaders but they don't seem to work when I build and run the app on my Android phone. The shader appears purple on the device when I run this application(I even used the Mobile shaders). Also, the trail renderer doesn't appear on the device but works perfectly on the Unity Editor.

I thought it was an issue with the device but when I made a test app using the trail renderer, the same shaders, and without the Qualcomm Vuforia Plug-in the trail renderer and shaders worked fine so it isn't the device.

Would this be an issue with the plug in or is there anything in Unity I can do to have the shaders and trail renderer work?

Thanks!
