I upgraded from a fitbit charge 5 which tracked my HR pretty accurately up to 180bpm however my galaxy pro 5 watch seems to cap my HR at 123bpm
Today in the Dr's my resting HR was 140bpm and the watch didn't pick it up. Is there a fault with my watch or is it a known issue? And what can I do to fix it? As soon as my hr goes above 123bpm my watch just keeps it there.
