I had no problem with the buttons on the Samsung Tab or on the LG G5 phone.
But when migrated the game to the LG G7, using 18.9:9 aspect ratio, somehow the buttons acted a bit off… a bit off to the right from their position. From chat I usually initiate an attack before manage to send RSS to a mate and such.
My suspicion is that the long and narrow screens are not favoured by WD. The event/atlas event screens don’t even show properly, the bottom of them is just missing since the game fills the full width of the screen (and no way to scroll down)
It’s certainly worth opening a ticket, maybe some screenshots can be attached just to give a little work to the devs, and help them with the visuals.
