iOS keyboard covering text box

When i tap on the text box for the keyboard to pop up, the text box remains on the bottom so the keyboard ends up covering it. It doesn’t raise above the keyboard like it should. This is extremely inconvenient as I can’t see what im typing.

This comment helpfully points out that as a temporary workaround, turning your device over once or twice can help make the text box appear in the correct place.
Update:
This issue was related to the iOS keyboard and should be fixed by updating to iOS 11.2+
