Keyboard Input Not Working on InputField with Ray Interaction on Canvas (Unity XR/Meta Development)

Hi! 

Are you using multiple active Input Modules? Unity generally works with a single input module active at a time. The Interaction SDK uses PointableCanvasModule .. which currently does not process mouse/keyboard input (we have a custom version in a sample project that supports this). 

You can use the sample project using the CusomtPointableCanvasModule for reference as a stop gap. This works with the old input system or if 'both' are active in the player settings. If you're exclusively using the new input system then you'll need to modify the script to extend from InputSystemUIInputModule instead of StandaloneInputModule :

Additionally, there is an issue with the TMP input field in Unity (losing focus) using a physical keyboard/mouse that you might run into when running your apk on the device  :

Hope that helps! : )
