Question is where does it break?
Is the issue on Garmin side not receving data or is it MFP not sending the data?
Anybody checked with MFP support?
Garmin is aware of issues with data not syncing from MyFitnessPal. We are actively investigating to determine the root cause of the issue so that it can be resolved as quickly as possible. I do apologize for any inconvenience.
If you are aware of the issue then why is it not reflected as a problem on the Garmin Connect Status page. Isn't that the reason such a page exists?
