I have noticed that twice I have started an activity and my cadence sensor, tempe and HRM TRI didn't connect to my watch. I also have noticed that after performing an activity that uses sensors leaves battery consumption at 2% or higher and a reboot is needed to get it lowered. I see that the lowest battery usage now is 1.7% and I was used to seen 0.3~0.4% when not doing any activities. Using beta 3.50 this started around beta 3.34 I think.
