I have my POH and Checklist on Good reader and find the same thing. Sometimes touching the screen does nothing.
Jepp FD so far I like, much better than their last TC app. New update has improved a few bugs, most notably not recognising navaids in the route segment. Still doesn't do airways though. But in terms of having an easy to carry solution to Enroutes, airway manuals and terminal charts it's ok.
