My Fenix 8 ran out of battery during a run. I stopped the activity once I got home and charged the device. The activity is saved correctly, but the metrics have not been updated to include the load from this session. This is a truly serious bug!

Hi there, can you please attempt to manually sync the Activity to Garmin Connect web to see if the metrics are able to be properly displayed? How to Manually Upload Activities to Garmin Connect

Unfortunately, it doesn't work. I’m attaching a screenshot of the situation.
Thank you for trying to upload the activity manually. The activity itself may still save and upload successfully after unexpected battery depletion, but certain performance metrics are processed separately. If the watch powers off before that process is completed then the activity may save without metrics such as training load and operating mode being calculated. Unfortunately, at this point, the missing training load cannot be recalculated.
The strange thing is that the graph displays the load, including the breakdown between anaerobic and aerobic components. It simply isn’t being added to the acute load, but the load amount itself is there. It is what it is for now—please take this into account for future updates.
