Just like Facebook and Instagram, WhatsApp introduced the Status feature some time back with which user can share their stories for a validity of 24 hours to their contacts. Currently, there is no option to have WhatsApp status automatically shared to another platform like Instagram.
The feature has not been officially rolled out by WhatsApp or by its parent company Facebook but it seems to be rolling out to all its users.
After experiencing the new feature, several users took to Twitter to share the news which led WhatsApp to trend on Twitter for some time. If you are also not able to see this new feature, try to update the application from your app store.
This new feature will allow the user to share their WhatsApp stories directly on Facebook with opening and sharing it on Facebook. It will appear under the status circle reading "Share as Facebook story"
Even, it the user delete the WhatsApp status after sharing it on Facebook through it, the Facebook story will still remain there until the user deletes it.
In 2014, WhatsApp was acquired by Facebook in $19 Billion and it is now part of Facebook along with apps like Instagram.
