The dark grey bar at the bottom of the screen with the FAQ, About, Contact, etc, is covering up where part of the messages are, and also where we reply to a message.
I was replying to a message just then but couldn't read what I was writing with the rest of it as it disappeared behind the bar.
Also as soon as I clicked Enter to go onto a new paragraph, it sent the message instead.
And now because of the bar placement being completely over the top of the message reply section, I can't reply any further to the message.
