Apple Watch and Tattoos

If I try and record a workout on a bike or walk apple fitness app pauses because I have tattoos on my wrist. If I go on a walk with or a bike ride and don’t record Apple Watch asks me if I want to record a workout. I don’t understand the logic of how this happens, the Watch knows I’m doing an activity but pauses when I want to but will record on its own when I’m not asking it too. Will apple fix this problem it’s annoying to do workouts on apple plus fitness and have it pause while my heart rate is up. Please fix this apple, as I believe it’s more of a software problem rather that hardware. Why can’t the Watch be programmed to stay on a workout with out being paused. I have read all the other discussions in this problem and suggestions like wearing the Watch tighter of locking the Watch but none of this works.
