In the versions 0.12.1-0.14.3,there are 9 hotbar slots,then I saw that the 0.15.0 beta has been released for Android. I installed this and tested it. I noticed that my hotbar slots is only 8. So that's why my Night Vision potion is not in the center. (5th Slot) The GUI Scale is in the lowest level but the hotbar slots is still 8. I tried to reduce the button size to the lowest and it's still 8 hotbar slots. I tried everything to fix this, but I can't. Please fix this and I will really appreciate your work.
