Has someone experienced this? I installed this keyboard from day one, on 22th Nov 2017, but 3 days ago, noticed that whenever the keyboard poped up for typing, the buttons on nav bar disappeared, that is, the nav bar was still there, registering touches in the 3 buttons, but no buttons visible, I reverted to stock keybd, But to no avail, unistalled a.i. type keybd, but no luck, ended factory resetting, and then, all fine, re installed the a.i. type keybd, and again the issue presented, so, I corroborated that this kbd is the culprit, anyone else has experienced this? I am very sorry as I use this kbd since my S3!!
