After you've customized your post, you'll be on the final "Caption Your Post" screen where you can add your caption, relevant hashtags, and select where you want to share your creation.
Tapping "Schedule Post" will allow you to pick a date and time for your post to share. The final "Share" button should change to "Schedule" once you've successfully scheduled your post.
Instagram Note: Instagram does not allow apps to post videos on your behalf. If you schedule a post to go to Instagram, we will send you a notification at your scheduled time to remind you to complete the post. If you have notifications turned off for Ripl, you won't see this prompt! We copy the caption you entered in Ripl, so simply tap the notification to open Ripl, then tap "Launch Instagram" and you'll be taken directly to the posting screen in Instagram.
Unschedule / Reschedule: You can unschedule or change the scheduled time of a post by going to your "Profile" on the home screen and tapping "Schedule." Tap on the date that the post is scheduled for and scroll to the bottom of the calendar to tap on the post where you'll see a calendar icon in the thumbnail which allows you to make updates or unschedule.
