Snapchat rolled out two features with an update on Monday that are sure to please users.
The first is “travel mode,” which users can turn on to make sure they’re using up less of their data plan while Snapchatting on the go. It works by forcing the user to tap a Snapchat to load it, instead of automatically downloading it once the app is opened.
On top of that, Snapchat also allows users to now add as many emojis to a post as they want (see above) by tapping a new icon in the upper right corner. Before this, users could only incorporate emojis on the pre-ordained text line.
