Keyboard not showing up in landscape mode in iOS11

I’m using Unity5.6.2p2, Xcode8.3.3. Currently on the iOS11 devices, when I’m in landscape mode and tap on the input field, the keyboard doesn’t show up. Does anyone have the same issue? Thanks!

Found out that Unity5.6.3p4 has the fix for this issue:

(933588, 944619) - iOS : Fixed the underlying behaviour of the iOS player in order to make the Unity window the key window after an orientation change. This was causing problems when, for example, an attempt was made to open a URL when launching FBlogin through the Unity Facebook SDK when in portrait only autorotate state.
