Automatic page scroll-up function was applied.
When you tap a line at the bottom of the page to enter characters, the keyboard appears at the bottom of the screen, but the screen automatically scrolls up. So, you can enter characters soon in the line.
In older versions, tapping a line at the bottom of the page to enter a character could hide it on the keyboard that appeared. Therefore, “a procedure to swipe up the screen so that the line is not hidden and tap the target line again to display the cursor” was necessary.
In V1.6, when the keyboard appears, the screen is automatically scrolled up by that height. As a result, it eliminates the extra steps described above.
