I'm sorry to hear that you've been encountering that issue. Using WiFi would almost certainly get around that issue, as the connection will be less fragile, but I understand that WiFi is not always an option. I will investigate this with my S8 Ultra to see if I can reproduce the problem. Let me ask this - you said the tablets have been left on, so I'm assuming they were connected over bluetooth long before you started trying to load the setlist, correct? How long do you think MobileSheets was sitting there before loading the setlist? I'm just trying to understand if there might be an issue with having a bluetooth connection that is sitting idle for long periods of time. Perhaps the tablet is actually letting the hardware go to sleep due to the inactivity and that causes a problem when MobileSheets finally goes to send/receive over the connection. If that's the case, I might need to force a heartbeat message of some kind to ensure the connection stays active the entire time (although this will use a small amount of battery). I am also looking to add bluetooth LE as a connection option, as this uses less power, and the nature of that connection may actually make it a better candidate for these types of scenarios. 

Thanks,
Mike
