For as long as I can remember, screenshots of any kind have never loaded on the Nintendo Switch version of Minecraft. This affects a lot of things, most importantly, the servers list, the character creator, and the marketplace. This is a big issue, as new players may have trouble finding an item, finding a specific server, or not knowing what a marketplace pack does. All other versions of bedrock don't have this issue except Nintendo Switch. This issue should be fixed before any new UI is implemented into the game. 

Steps to Reproduce: Open Minecraft on Nintendo Switch, then go to either marketplace, character creator, or the servers list.
