So someone's shared a list with you, and you want to make sure everything's all up to date? Here's a crash course guide to syncing on iOS, which will help you be N'Sync by the end of it!
1. First, go ahead and open up either your Shopping, Pantry, or To-Do List. We'll go ahead and open up our Shopping List.
2. Once you've opened the list you'd like to share, go ahead and tap the button in the top left-hand corner (3 horizontal lines).
3. Then go to the section, Actions, and tap Sync. Doing this will update your list, so you'll be able to see whatever items might have been added to the shared list.
Once you've tapped Sync, your list should be totally up to date, so you can get your shopping on!
