When accessing chat from within the Stack Exchange app, no keyboard is brought up when trying to add a message or edit an existing one. I had to access the chat via a web browser external to the app in order to get access to a keyboard in order to reply. I exited the app numerous times and even got rid of my third-party keyboard to make sure it wasn't just that. Nothing worked to fix it.
Here is a quick demo.
- App Version: 1.6.6.2
- Device: iPhone 7 Plus
- OS Version: Version 11.4.1 (Build 15G77)
