Recently my Blaze has been taking between 8-12 minutes to pick up my heart rate. I don't wear it all day due to my job and fear of damage. Regardless of it being on my wrist all day or putting it on just before exercise it takes ages.
This is collecting incorrect data on heart rate zones and calorie burns are less than 50% of what is recorded on the spin bike.
I have restarted it which hasn't fixed it. The green lights function fine
