As mentioned in my Reddit post:

https://www.reddit.com/r/NintendoSwitch/comments/8u3dri/its_been_almost_a_week_with_the_new_minecraft/

Host had a texture pack loaded. I hadn't downloaded any when first started so it popped up and asked me if I wanted to load and join. Sounded like a good idea. It never loaded, even though it was 10mb, and not only that once it did let me into a game the dl had been corrupted as icons were popping up with a colored square. I had to stop, delete save data and then made sure I loaded all the texture packs I had available before joining any games. I have a feeling that the texture pack if loaded before starting a game will come from the host of the game and the transfer is then iffy especially if their connection is already taxed. The timeout seemed pretty long when I was sitting there waiting for a single mb to download.I will create a new issue for the long wait to download the 10mb pack.
