Minecraft – Despawning problem in Minecraft

I think the "Restore Skins" button is used if you have previously purchased skins but the app is showing that you still need to buy it. You don't need to press it if you just want to apply a skin.

• To get out of the "We're restoring skins" message, close the app. Don't just press the home button, make sure it's actually closed.
• Open the app again and tap the skin you want. The free ones don't have a padlock symbol next to them.
• Press Back. Your skin should be applied.
• You can check your skin by switching to third person or by tapping the armor icon inside your inventory.

I had the same problem too but when I switched my skin back to the default Steve it seemed to load up and work fine.
