onTap not being called in Sim

The behavioDelegate onTap() event is not firing on a touchscreen device. Any screen tap raises the onKey() event with a key value of 255

Testing the tap function in my app on Vivoactive HR and VenuSq  in simulator, the onTap() event is not being called.

The app builds and runs correctly on the device (only have the VA-HR to test on).

SDK 6.2.1

Mac Ventura 13.3.1 

It appears to be a new issue, it was working fine on earlier SDK's during development, Also fails in 4.2.
