When I switch Layout Mode in Tab UI to Mobile Browser, Screen grid with search request does not display in browser, only header and detail grids. Does it not work in Mobile Browser. Also had to move linked Detail grid to bottom of Header grid, as it would not display to right.

Never mind. The tutorial data had search criteria, my copy did not. I was looking at tutorial data against my replication of tutorial and I must not have put in search criteria. But you need to put any linked grid on bottom of main grid for it to display in Mobile browser.
