There are several issues that I have experienced with the new version as well as in now old versions of minecraft bedrock on Nintendo Switch including:

• Game freezing after exiting and reentering another players multiplayer world
• entire switch freezing, requiring force restart, after closing the game
• Marketplace not loading images or text correctly
• Marketplace showing blue "!" even when there are no updates for owned packs
• Freezing of switch when going to the friends menu of the switch homepage while game is running in the background
• Skins taking insanely long to load or refusing to load without a game restart
• Slowing of system when opening or closing the game
• Crash during skin editing
• System freeze during skin editing 
• System freeze when opening Nintendo switch settings while game is running in background
• Console lag while game is running in background
