Temporary loss of all sensor reading by Fenix 5x during activities

Hi Guys,

From nowhere today was the second time since Saturday 27th that my Fenix 5x stops reading all sensors for moments ... 

The first one bellow was at the beginning and the second almost at the end... 

Nothing has change in my setup or environment... funny though the apps Rouvy and Sufferfest kept reading everything normally trough a pc/ant+ sitck... so it´s  not about the sensors.

Does Garmin update hub sensor etc with AUTO UPDATE set to OFF? I'm holding on 19.10.0.0  due the several 20.00 complains.

Thank you,

I have to say that this has never happened before.
