playTone() oddities on FR165 device

Hi All,

I've noticed that on my Forerunner 165 (device), Attention.playTone() is not able to play any of the pre-defined TONE_* values, but is able to play a custom tone profile just fine.

This is the exact opposite of what I expected after reading this thread:

The ToneProfile does not work on Venu3S - Connect IQ App Development Discussion - Connect IQ - Garmin Forums

Is this behavior expected on FR165?

Thanks,
