First it was Facebook Messenger for Windows 10 Mobile and now the official Facebook app for Windows 10 Mobile can also be downloaded by using a simple trick it seems. This Facebook app is Windows 10 UWP app from Facebook and is already available on Windows 10 PC. So, if you have it downloaded on your PC you can just go to My Library in store app and install it on your Mobile too.
Alternatively you may need to change your region to US or Germany and try to install it. In our case it worked without changing the region and by going to My Library where it was listed as “owned app”.
Facebook for Windows 10 Mobile changelog:
The app is fully-featured with features like Reactions, new revamped UI and more. Check some of the screenshots above. Even the notifications have swipe to reveal hide and More options feature.
