Once you have a post queued or scheduled, you may want to edit the caption, the time it's meant to be shared at, or cancel the post altogether.
Step 1: Tap 'My Shares' at the bottom of your screen
Step 2: Tap 'Queue' to see your queued and scheduled posts
Step 3: Tap on a queued post for which you would like to edit the queue time. Here you can edit the caption if you chose.
Step 4: Edit the scheduled queue time by scrolling to the bottom of the caption and clicking the edit pencil icon. Click on the date and time to adjust accordingly and then hit Save.
Your queued post will be moved to its new queue time or will be removed from the queue.
