Massive performance problems with Minecraft Bedrock Edition on Switch

Dear Mojang, I and my friends have massive performance problems with Minecraft Bedrock Edition on the Nintendo Switch; My game often needs more than 1 minute so start. Sometimes, it doesn't even start and the game crashs and I see "an error accured" on the screen. When I'm in the menu, the game needs about 15 seconds to show the settings, trophies etc. When I'm on a server, it is very laggy and I often die because of the lags (I have a good internet connection with my switch). When I set blocks, they sometimes disappear. Sometimes, the games also freezes for 30 seconds or more. That's extreme annoying when I'm on a PvP Server. I also can't navigate with my stick in the inventory; I have to use the D-Pad which is very slow. And when I'm on the left side of the inventory and want to go to the right side, I can't just press one more time to the left; I have to go the whole way to the right side. And I/my friends sometimes can't join to my friend's worlds/my world even though online playing is on. Please fix these problems as soon as you can because the game is basically unplayable for me at the moment and I love Minecraft. Thanks for reading and sorry if my English is bad.
