Won't allow me to sign in

The switch takes forever to load Minecraft and when it does it tells me that it cannot sign in to my Microsoft account. I paid for a switch online account so I am losing money off this bug and it takes up a lot of time. I have only managed to sign in a few times and these were few and far between. Please prioritize this bug and fix it as soon as possible. I enjoy the game and all but it really sucks when it doesn't work. I also deleted several worlds and now only have ten worlds and it still won't load so it is not a memory problem. Resolve once problem is fixed and please fix soon.
