I just removed myself from the Beta. If that interface is not fixed when it becomes mandatory it will be the end of my LNK playing.
My complaints are probably the same as listed here by others:
Beta freezes and/or is way to slow
Cannot copy/paste messages
Map seems to always reaet to your castle
Scrolling through castles never goes in order. Not sure what order it is using but it is not scrolling by name
Setup of interface is counter-intuitive. It seems like a bad hybrid of the mobile version and the PC version
Attacking and synching attacks is very slow
