When it comes to swaps, any that have not gone through will still appear in your schedule with a dotted line around it. As a pickup may process for approval, you will receive Prospr notification informing you of your schedule changes. If the swap goes through, the shift will no longer appear on your schedule.
Your requested/unapproved time off will appear yellow on your schedule. Once the request has been approved, you will receive a notification and the dates will change to "[Type] Leave" in your Schedule (blue).
