Sorry, Again I'm using Android 13 device.
For some reason I'm using a 64x64 & .png image.
I guess I can't do anything just suffer & wait 'till mojang fix it
It is a 64 x 64 image & yes, it's a .png image bc mc just support.png images when it comes to skins
Nah, you can just close the launcher & re open it.
Kinda weird, but this might get common in the future though.
