Probably this may be corrected in the current Logos5 beta (but not the current L5). And maybe already reported.
When you click on a library item in L5, it shows all the mobile apps but not Noet (the icon). I'm guessing it's Noet. There's no Reformation app either, but maybe L5 doesn't know about that one.
I put it in the Noet forum, since I doubt it'd be a priority in Logos5 (mucho bigger bugs being swatted).
