Does Forerunner 55 supports Gyroscope Data and Max sample rate of 100Hz?

In announcements about SDK 6.3.0, he said the max sampling rate is now 100Hz for Acceleration and Gyroscope data.

But when I tried with Forerunner 55(simulator and device), it still works with the max sampling rate 25Hz.

And also, Forerunner 55 always has "null" for SensorData.GyroscopeData.

In API doc, GyroscopeData is supported by Forerunner 55. But I don't know why it does not work.

I ran the app with Venu3 and fenix7 for test. It worked well. Both max sample rate 100Hz and gyroscope worked well.

- Is there any way to get Gyroscope data in Forerunner 55?

- Where can I check the "real" supported devices for these features?

- Is there any sample application code using Acceleration and Gyroscope data?

This is the code I used for testing.
