Perhaps it's just me. And perhaps there's an older thread on this; please redirect me. 
I'm sure older versions of the iOS app were pretty robust when it came to manually typing the passage I wanted to jump to. I could offer 'Rev' or 'Rev4' or 'Rev7.9', and they'd all work (though, of course, taking me to different places).
At the moment (v5.0.4), I can't get the middle syntax working: book+chapter. Although it works with rare combinations (e.g. 'Gen2'), I generally can't get anywhere with this. I can get 'Matt' or 'Matt15.24' but not 'Matt7'. By extension, 'Matt7.1' does work, but it's frustrating to add.
I'd peg it as some kind of server issue. Everything runs fine (though a little slower) when I'm connected to wifi. But I'm often offline, as when in church or class, and that's when the functionality differs.
Any suggestions?
