Apple Watch not generating cardio data - cardio recovery and fitness

Apple Support - I am writing to bring to your attention a critical issue that multiple users, including myself, have been experiencing with the Apple Watch 7.

Over the past weeks, more than 200 users have reported that the Apple Watch is not consistently generating cardio data. However, I have seen no response from Apple.

This issue manifests in two ways: the cardio data is either entirely missing or is highly inconsistent. I personally encountered this problem during my most recent 30-minute run, where no cardio data was recorded.

While there have been instances where cardio data was successfully captured, it appears to be an intermittent problem. This inconsistency is causing frustration among users who rely on the accuracy and reliability of the Apple Watch for their fitness tracking needs.

Here are the specific details of the devices involved:

• Apple Watch: Model 7, version 10.2 (21S364), Model A2477
• iPhone: Model A2849, iOS Version 17.2.1

I kindly request your prompt investigation into this matter to identify the root cause and provide a solution. Given the widespread nature of this issue, a swift resolution would greatly enhance user satisfaction and maintain the high standards associated with Apple products.

Thank you for your attention to this matter. I appreciate your dedication to ensuring the optimal performance of Apple devices.
