So, you've moved and you've realized your posts are still showing up in your old 'hood! No worries, we can help you fix this and start engaging in your new community!
When you go to create your next item post, tap the map on the item creation screen and move the map to reflect your new posting area before you publish the post. Once the post is published, this will set your posting location for all subsequent posts.
To update your previous posts, tap each one, tap the edit option and move the map as above, save the edit. Note: This will update the location for the posts, however, this will not change the posting location for new posts and the step above will still need to be completed.
