I can't upload skins from the Minecraft Launcher. A few months ago I had an issue with my computer and I had to format it. I had to install everything again including Minecraft. Before this, I had uploaded skins with no problems. But, every time I try to, I get a message saying "unable to save skin". I've tried logging out several times, as I saw in similar posts, but it didn't solve my problem. I've also tried with several skins, just in case. I can change my skin from minecraft.net, by the way.
Hey, I am happy you got it to work on our website. We are aware of the skin changer not fully working in the launcher, and will address it as soon as we can. I'm closing this bug and redirecting to MCL-14579 where we track the status 🙂
