Going through menus takes much longer than before, Cross-platform players cant join switch worlds.

For about a month now, Minecraft Bedrock for Switch has been running really, really slow through the menus. Opening the game takes 52 seconds, loading a basic flat world takes 49 seconds, it takes 20 seconds to open the setting whilst in a world and the game runs much slower in areas then it did before. Also, when people on other platforms try to join my world, at least 80% of the time they cant join it and the game says 'unable to connect to world'. This has been like this since launch.
