Instagram releases a new WhatsApp-like live-location sharing feature
Location sharing features are currently only available in select countries, but the list is unknown yet.

Instagram is now allowing users to share their live-locations with friends. While this feature is already being used on other social media channels, it is new to Instagram. The feature works within Instagram’s direct messages, which also gets a few other new features, including sticker packs and nicknames.
Now in your DMs, you can share your live location for up to 1 hour or pin a spot on the map to coordinate arrival times, activities or find each other in crowded spaces - perfect for concerts, outings, or other gatherings with friends. Spend more time together, and less time coordinating.
