When trying to use box selection for some reason only the top vertex is being selected. If anyone can help that would be great. Here's a video of what's happening. I'll try to update if I figure it out.
Thanks for checking this, I figured it out just a few minutes after posting this. The problem is that I wasn't in mesh viewport shading mode. I had trouble selecting faces earlier in it, so I switched out, but apparently you must be in it in order to select through objects. Hopefully this can help out someone else who doesn't follow the directions like me 😏
