This has always been hit or miss for me, tapping the little Circle-i, Info Button: Half the time it opens the resource rather than the info panel. Please consider making it so that the Info Button sits on a larger rectangular (invisible or translucent) button so that tapping anywhere to the far right opens the info panel.
Also this is more consistent after the addition of the reading progress indicators. When you tap on the indicator, nothing happens. If you tap to the right of it, but not on the Circle-i, it opens the resource. IMO, tapping anywhere to the right of the progress indicator should open the info panel.
Thanks.
