First of all let me I really do love this app so far. For a beta it's great!
One issue I'm having trouble with however is the find presentation part.
First of all I'm using Mac.
Second, in the edit portion after I built a slide like a Scripture reference for example I made sure that the "signal" was on, and once in "on air mode" the proclaim icon does flash in the corner.
Now on my iPhone once I've launched the logos app initially there was a find presentation selection, upon select it I was asked if I wanted to allow it to find my location to which I said yes. However, that's all that happened. I was expecting some sort of window to launch asking me if I'd like to join this presentation or something, but nothing like that has happened. I have tried this both on a 3G network as well as being on the same WiFi network that the church Mac is on that is actually running the presentation. I'm sure I must've missed something on the settings that will allow users to pick up this signal but I can't seem to figure it out. I'm actually trying it on two different Macs a MacBook Pro 2009 model and a brand new Mac mini. I've tried to find the presentation signal with 2 different iPhones. An iPhone 4s and an iPhone 3GS. All have had the same results
On a different note, the iPhone and iPad remote apps are BRILLIIANT!
