I don't know if this is really a bug but there's no button to load my own skin

My game had previously been glitching, I couldn't even open the app until the most recent update, but when I did it wouldn't let me open any worlds until I chose one from the programmed list. If this isn't a bug, it's an increadibly unfair update for people who use MC for role play and more immersive experiences. Mc is supposed to be about freedom to build and live essentially in a whole new world, so I feel this should be fixed quickly, and if others are experiencing this I'm sure they feel the same.
