Hello,
We use Proclaim and have been very happy with it, and in the past, we have loaded sermon presentations into proclaim and gave the pastor control on his iPad with the Proclaim Remote app. This has worked very well for us up until recently, when the app inexplicably stopped working. We have tried it on multiple devices, but every one of them gets an error when trying to change slides.
I don't think it's a network error, as we are able to see and follow the current presentation (if I change slides on the computer, that's reflected on the mobile app, with only a minimal delay), so the device and computer are definitely still communicating.
We had to give up on controlling Proclaim with the remote app and just go back to running Keynote presentations from the pastor's iPad. Any insight as to why we are having this issue would be greatly appreciated!
