Is myfitnesspal down? The garmin status doesn't show that, but nothing from myfitnesspal syncs across. See attached image. I meant March 14, 2016 in the title.
I have the same issue, however when I choose 'Go to full page' and then click 'Go to reports to see more data' down below the report does show the right data from MFP.
It could be a problem on the Garmin Connect page, not so much the synchronisation itself.
How long it takes depends on what the issue is.
I can't now even get to the Garmin Connect status site. Is it down? I am using the url http://connect.garmin.com/status/ and it redirects to the modern user interface.
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.
