I just did another batch import of around 3700 files without issue. So something is interrupting the connection between the companion app and your tablet. It could be software-based (firewall, anti-virus, etc), it would be router-based, or could it even be device-specific, depending on the hardware, network drivers, etc. I don't know what's causing the interruption, but the companion app doesn't currently have reconnection code in place to try to recover after a socket failure like that. That's something I'll have to add at some point. If this is problematic for you, you can also consider importing through the cloud (Dropbox, Google Drive, OneDrive), as you can still batch import through the cloud.
