Why am I unable to reply to some Facebook Messages?

Due to new API changes by Facebook, you can reply to a message within seven days of receiving it on a third-party app. However, after the seven day window, you cannot reply to a message sent by the Facebook user through Zoho Social's chat.


For more information, read Facebook's policy on message tags.


You can head over to Facebook's web browser or messenger to natively reply to these messages.
