Also having this problem with the switch. When I go in on my account (switch owner) the store will pop up after a minute or so and I can access skins. However, if my child logs on under their account (child account on switch), no marketplace or skins are available. They are just all grayed out. No other accounts on the switch can access the skins when loading Minecraft. I've tried re-downloading the game multiple times an clearing the cache from the switch accounts.
