Instagram update brings support for landscape and portrait images
Since Instagram Direct was launched for everyone back in April, developers have been trying to further enhance users experience by adding new features and improvements.
Furthermore, the update brings support for links in Direct, which means that Instagram users can now share websites with their friends and preview them directly in the conversation. The same goes for phone numbers and addresses.
Support for landscape and portrait images in Direct is already available for iOS devices with Instagram version 10.22. However, Android users will have to wait a while longer for these new features to arrive. On the flip side, links in Direct messages are available on both mobile platforms.
