Some feedback for installation on iOS 11 and 12
iOS 11, iPad: I also got that message that my library is empty. I let it be, it itself removed that message after a few seconds, showing these wavy lines above again, that looked like a syncing approach (not really clear), and then the same message popped up that my library was empty. Tapping on the sync icon in the upper right worked the first time though, doing apparently something different and came back with my library in quite a short time.
iOS 12 beta, iPhone: Interestingly, I did NOT get the empty library message here and the syncing of my library seemed even faster? Also, I had a percentage display in the lower screen that I’m not sure was there on the iPad?
Search engine (both iPad,iPhone): It seems you are using a different search engine on iOS than on the web client, which can be confusing when the same search term is used and returns different results.
In my example, I simply search for my last name “Aye”, and on the web it seems to first find papers where my name is found as a whole word in the author list (while ALSO marking things inside words like “layered”, would be nice if we could control that btw), but on iOS, it would not first list the papers where the whole-word author name matches my search term, but instead brought up a paper where one of the authors is called “Hayes”. Would be best if the search works the same way on all systems, I guess.
All for now, thanks for letting me beta-test!
