I have a Sense 2. Since the latest update the Cardio Load and Readiness markers do not work at all. They are blank. I can click in and I have met all the requirements but it kicks me out or says try again.
My cardio load isn't working either. I did have a readiness score, though. I met all the requirements as well. Says "no target" and to wear my device to track progress. I've had my device on and charged.
