Hi, I often use the remote app when I am leading worship and there is no-one else available to change screens for me. Most of the time it works perfectly however occasionally everything freezes up which is very inconvenient when in the middle of a song. Mostly it unfreezes after a few seconds then works normally again until the next time. Last Sunday it occurred a number of times during the service - probably the worst instance I've had. Does anyone have any suggestions as to what this could be? My phone on which the app runs is reasonably new so I don't think the phone is at fault. I don't think I've ever seen things freeze when operating the service directly on the laptop either, so I assume it is an issue of communication between the app and the laptop. Thanks for any advice you can offer.
