Quick reply = no keyboard
I can second the post of this guy - Quick reply - Keyboard Missing
Where did it go? Running iOS 8.4
This feature is used all the time by minions in nearby departments, I'm in IT, so they want me to find a fix...
Rebooting the phone will bring the keyboard back for a while, but it's not permanent.
Bug report has been filed already
Is there anything else to try?
iPhone 5s, iOS 8.3, At&t
