Sorry everyone! We have discovered that the function which allows you to add your Facebook friends to LINE has not been running correctly and have had to discontinue it. This function was released on versions 3.0.0 and higher for Android on 26 November and we stopped this function on 28 November at 3am (JST).
We are currently discussing how to fix and improve the function with Facebook, as well as readying the function for the iOS version of LINE.
Please rest assured that this only applies to the function to add your Facebook friends. So you can still register as a new user as well as carrying your account over with your Facebook account.
Also, any Facebook friends you may have added to LINE will remain on your friends list.
Once we have any new information about this function, we will be posting it on here!
Thanks for reading!
