Great Question! First, a little explanation on how things work. When you sync CrewBuddy with CWA, it will upload your new schedule to be viewed by your buddies. So, if your buddy hasn't synced CrewBuddy with CWA in a while, then you're seeing an old schedule.
Just ask your buddy to do a quick sync with CWA and you'll see their latest schedule!
Tip: Scroll down to the bottom of your buddy's calendar. There you can see the date and time they last synced with CWA.
