HRM Belt Decathlon not work with Suunto Race

[Sloan FrenChieDog]

I just buy the Decathlon HR Belt to use ZoneSense function

![On the Suunto app, I have no problem. But with the race, on the activity selection screen, the belt icon is not stable. And during activity it’s the same, the value is displayed then goes away then comes back at regular intervals.768969560.355435.mp4

Do you have any idea how to fix the problem (I’ve already done a soft and hard reset)? And do you know if this HR belt is compatible with ZoneSense ?

Thanks
