Hi, i'm Bruno again, this time, i was playing mcpe in the max Gui scale, 2 days after, i started minecraft pe, and i noticied something, the Gui scale is small than 2 days before, and i checked the Gui scale, and is normal! Max Gui scale like 2 days before, but is smaller than 2 days, i don't know If this is a bug or something, but i like to have a bigger Gui scale.
