I provide you with two videos showing how it works before and after reinstalling

It works when I reinstall but if I close the game and open again it doesn't work again.

My problem is with Android version.  Does not react any option.

If this is any help, I began to have issues with my skin last night and the end of yesterday. Going from Alex to Alex skin was the main issue, resulting in either a steve skin model instead of an Alex or just not changing at all. I was able to fix this through restarting my laptop and immediately uploading a new version of  the skin I wanted on the launcher. 

However this morning when I logged back on to my server, my method no longer worked. It seems that the Alex model itself is inaccessible. Hope this helps~

((edit: I just noticed I still have difficulty even changing the skin at all)
