It's been about two years since I bought add-ons in Minecraft for my skins and everything works great except when you create a new world with the experimental options, and when you include mods the skins stop working and it appears without the add-ons. I paid to be able to use those add-ons when I'm playing and not being able to use them is annoying. I've been there for several months so I hope they fix that soon. I leave a photo of a world without the experimental options and what my skin looks like.
