There is nothing in this app. When I open it, it shows pages for Maseches Kiddushin in the table of contents. If Iclick on one of the pages in the TOC, I just see a blank page with a forward slash mark at the top. No Siddur and no Maseches Kiddushin. Just a bunch of pages of nothing. I dont know why Kiddushin comes into this. The whole benefit of this app is having the Artscroll Siddur without the baggage of the Artscroll digital library app.
