This isn't really a bug but more of a tip that is no longer accurate, but I wasn't sure how to mark it properly. One of the tips that shows up when loading says to go to www.mixer.com/minecraft to see streams. However, Mixer is shut down and this goes to a page about Mixer being gone. I'm not sure if this is only on the Nintendo Switch version but this might be why people keep reporting bugs about Mixer to this website.
