At the bottom of the learning screens, like line up and puzzle it can sometimes be difficult to hit the buttons/icons at the bottom of the screen accurately enough for the device to register the tap. I have an iPhone 13 mini and it seems like the buttons are very close to the bottom of the screen almost interfering with line at the bottom for swipe up. If I look at other apps the icons are spaced up from the bottom more than on Remember me. About 1 in 5 of my attempts are a miss which I have never experienced on any other app. I wonder if this is specific to my device or a general issue.
