Sharing a collection on iOS
If you want to quickly share a collection with someone you can do that straight from your device with a few flicks of your thumb.
First, view the collection you want to share and then press the ellipsis button in the right corner and press share when the menu appears from the bottom of the screen. Then you can choose how you would like to share the collection: via AirDrop, send a message or email, copy a link, or even post the collection on social media.
You may need to change your privacy settings to allow others to see your collection. Learn more about collaborating and privacy on Dropmark here.
