Ever since my phone updated its OS yesterday, I haven't been able to use my S pen for the game. Using the S pen only zooms the game in and out, so I'm forced to use my finger which is too wide for the screen and I end up merging things I'm not supposed to merge or moving things to the wrong space. The game is not fun to play and I won't be playing it again until the game has been updated to be compatible with my Samsung Note 20 Ultra's pen. Please work on it.
