We have been using this program since it came out. Over the last few months a number of us can no longer connect to each other.
Weve attempted to concert support, it often takes weeks to get a response and basically the only response we got is "blame Apple iOS 7".
Emailing lists have been difficult as well. It just seems like they are having a tough time getting the most important function to work properly.
If your going to use this for persona use, go for it! If you want to use it in a worship team setting, proceed with caution.
