I am the happy owner of a brand new FR965 that I've been using for the last 4 months. I am very pleased with the overall performance but I've been struggling with a recurrent problem since the 1st time I used it. With a ratio of 1 of 3 or 1 of 4 times and only for Strides Repeats and in the middle of the session the HR sensor starts reporting very wrong measurment. Below screenshot is for today session, 14 times 20secs run and 45 secs recovery and reaching 10 times the HR sensor started showing 60-70bpm. I have tried adjusting the watch to my wrist again, cleaning my wrist and the sensor, changing the watch from my right to my left hand wrist and nothing fixed the problem, At some point after 2 o 3 min it started reading the correct hr again. Another time the only solution was to restart the watch. I have had long training sessions of around 2 hrs and HR is always accurate, I face this problem only with Strides repeats sessions. Before FR965 I used a FR245 for more than 2 years and never faced this issue, it worked flawless. Has anyone else had this problem?
