Once you open the MEL section click on the three blue horizontal bars in the top left corner. If they aren't there, tap the screen and the top task bar should drop down with the blue bars. When you click the bars you'll see some things come up at the bottom left of the screen. One of them is a spy glass. Tap the spy glass and the search bar will come up in the top left of the screen (below the blue bars you tapped before). Type in MEL # and hit enter.

And yes, I agree. Not a fan of Docunet. Navigating it isn't as clean and intuitive as Comply IMO. I'm sure I'll get used to it at some point in the next 29 years when I retire.
