I was so bummed when presentation mode disappeared! I had started using it a bit with plans to use more. I led a meeting with it a few weeks ago, then I couldn't the next! I understand it's still available in computer version but I used it in settings where a computer isn't as practical and also as a way to just make my notes easier to read (so not only to display my "slides." This is something I'd love to see brought back, without it I'll definitely begin using this app less as I was excited to continue implementing the tool.
