I was in the field today with an mmpk loaded on to 3 Windows tablets. The map loaded fine on all three at first. Then after closing the app, putting the tablet to sleep, and restarting the app (a process I need to go through because of another glitch where the app loses it's connection to the internal GNSS receiver and won't reconnect if I put the tablet to sleep while the app is running) it was suddenly signed out. This happened to all 3 tablets within about an hour, making them all useless. There is no way to sign back in while not connected to my organization's network.
