I went for a long walk yesterday (Sunday 24/04/16) I did around 24,000 steps for the entire day. I recorded this walk as a hiking activity.
My Forerunner 235 has sync'd multiple times, including today's steps (Monday 25/04/16) but has put Sunday's steps as zero on some screens, but as 24,000 on other screens. I have attached screenshots to show this. All screenshots are taken at the same time, the FR235 was sync'd over 24hours ago and has been sync'd multiple times since and shown all other data with the exception of he steps.
The recorded activity, distance and all others bits of information have been recorded and show on the garmin connect application.
On image 1 below on the 30 day chart at the bottom you can see Sunday shows zero steps
On image 2 below you can see my total for the week is 51k, but this does not include Sunday
Image 3 below shows April 24th (Sunday) as having zero steps.
Weirdly when I click on April 24th as shown in image 3, it brings up image 4, which shows my steps count from Sunday.
Images 1-3 show errors on those screens and image 4 shows the only correct screen.
