Apple BT trackpad connected to Fire TV stick; will scroll but can't select

I used settings.apk to connect an Apple wireless keyboard and trackpad. Everything works fine so far except that tapping the trackpad does nothing. I can scroll around perfectly but can't select anything. I've tried it on all kinds of surfaces, tried restarting the Fire TV stick... anyone here have a solution to this?
Thanks
