Hey @MojangSupport I have a problem related to putting a custom skin. On the minecraft launcher, it appears that I have the skin that I put on, but when I go directly to minecraft, the Alex Skin appears... I would ask you to give me a solution to this problem if possible! Thank!

Something is likely interfering with Minecraft, such as incompatible software or malware. Remove any third-party Minecraft software and perform a malware/antivirus scan. Let us know if the issue persists after a scan and cleanup! ^AM

Hello again, I tried what you told me and the Alex skin still appears
