For anyone experiencing this issue and reading this thread, i would just like to give a brief update as to my experience with Apple support. After numerous telephone calls with various Apple support senior advisors, remote diagnostic test(s) of the watch, screen sharing with advisors to check all settings, and submission of diagnostic log(s) to an Apple engineer, they were not able to resolve the issue or give a likely time frame as to when a resolution would be reached.
Given that the issue originated in September 2025 and Apple support could not provide any indication of if/when the issue would be resolved, as of January 2026, I made the decision to replace the watch with a Garmin. I have been able to obtain all stats immediately following upload of a run using the Garmin watch.
Whilst I understand and fully appreciate the importance of providing data logs to help identify where issues are occurring and improve software etc., my experience with Apple support felt lacking in the actual support aspect and more heavy on providing data, with no insight provided to me relating to the submitted data.
I logged more than 5 hours of my time on the phone to Apple senior advisors and messaging Apple geniuses, and significantly more time including independent trouble shooting.
Ultimately, if you are experiencing this issue, yes it’s worth checking with Apple support in case it’s something basic. However, based on my experience, I would be wary of how much time to invest when it’s something more complex and they are unable to provide any indication as to resolution time. We are supposed to be the customer and not the employee.
