Firmware version: 16.17
HR Band: Polar H10
Started lactate test correctly, but when I was asked for the latest HR interval, it stucked on 169bpm (test said I had to reach aprox. 183 bpm and believe me I tried it hard), after the 3 minutes, test said it failed to find lactate threeshold and HR status started working again on real time.
I am attaching a screenshot so you can see what I mean
PS: i have reached more than 183 bpm during normal training in the past, but I think it was with an older firmware version
