Connect Moblie IOS calendar

The app calendar shows other stuff than just activities and workouts like Steps, Move IQ events, Sleep score, Weight and a lot more that the web calendar doesn't show. Click the 3 dots in upper right corner to filter what you would like see.

The web calendar only shows activities and workouts.

None of the entries in your app calendar are activities or workouts. So, everything looks like it should.

Thanks.

But  the August entries on the my mobile connect APP are other people's not mine, how can I delete it?

How do you know they are from someone else? Is it a used watch?

You can't delete health data. Move IQ events can be deleted. Click on them and see your options.

I had reset it to factory settings. I don't konw why these data still in there.

There are two options when you do the master reset - with deleting all data, and without it (which is usually the default option). So if you did not explicitly select the option to delete all data, the data of the previous user is still on the watch.

Another possibility is that you added the watch to your Garmin Connect account before doing the reset.
