New No Bluetooth Connection With Suunto Spartan Sport Smartwatch

[July9]

Hello

I have a Suunto Spartan Sport HR, which connects with Android phones through Movescount App.

My Xiaomi Redmi Note 4 Global with MIUI global 8.2 estable (8.2.10.0) does not connects with the smartwatch. I have tried to connect it with my friend's LG stock Android and it works, the smartwatch gets paired with the phone through Movescount App (bluetooth connection).

Of course, my Xiaomi is not hidden in bluetooth settings.

What can I do?

Thanks
