When I receive a text or message on the Facebook messenger app through my lock screen, it will not let me quick reply when my phone is locked. It just comes up with 'clear' reply does not appear. I have an iPhone 6s and my phone is all up to date.
Why will it not let me quick reply on lock screen?
User-centric queries/comments such as this are perhaps best put to Apple's public community support forums, where Apple tends to monitor user comments, and/or Apple's twitter support account, vs. risking off-topic here in the dev forums, thanks and good luck.
