Hey! I haven’t seen any official release notes yet for firmware 50.30.3.0 on the WHOOP MG… looks like WHOOP hasn’t shared specifics on what’s in this update. Usually these updates include general improvements like bug fixes or better data accuracy, but nothing detailed has been posted so far.
If your heart rate still seems off after updating, double-check that your app’s fully up to date and that your band’s snug and sitting in the right spot. That usually helps!
