Custom made skin from Minecraft shop not loading on realms (Minecraft PS4)

I play on Minecraft PS4 and I am the owner of a realm. I am the only one in the realm who plays on a PS4. I used to be able to play using my skin, but now whenever I join my realm, I'm always a steve or Alex. When I customise my skin in the dressing room and add items, it doesn't show and I'm still a steve or Alex. However, if I join my own world or a friends world Im in my custom skin.
