FR245M no longer connects to my Polar H10 chestband.

Hi all,

As written in the subject title, my FR245M no longer connects to my Polar H10 chestband which I believe is related to the latest 4.2.0 firmware update. It doesnt connect to ANT+ nor Bluetooth. I deleted the sensors and it doesn't find the H10 when trying to connect. I have checked with other apps, so I know that the H10 have battery and function as it should. Also, the funny thing is that if I click on an activity it finds "External HR device" although it's not added as a sensor.

My spouse have had a similar issue since 4.1.0 was rolled out on her FR245M, she uses a H7 chestband (it do not have ANT+ but bluetooth only)

Anyone with similar issues?
