Your footprints are sorted by the date you assign to each one. If they appear out of order, it’s due to incorrect date or time settings.
To fix the order of your footprints, edit the one that’s out of place and select the correct date. If multiple footprints have the same date without a time, they’ll be sorted by their creation date. To adjust the order in those cases, please add a time to each footprint.
Timezone issues: Please be aware, that 9 am in one timezone can be later than 10am in another – even on the same day!
In your “Home” feed, your own footprints are sorted by footprint date, while posts from other users are sorted by creation date. This ensures you don’t miss newly created footprint posts from others, even if they’re dated in the past.
