Less than 2 months ago I bought a new Nokia 3.1 Plus running Android Pie. So far I've been able to download 2 updates with no problems. Yesterday another one popped up and I haven't been able to download it. I keep getting this message "Previous DM session is still working. Please try again later." I searched online, didn't find much. I did find that DM stands for Device Management and supposedly means something running in the background. I turned off all of my backups. Still the same message. Has anyone ran into this problem before? Or anyone have a fix? Cricket CS was no help as usual and told me to contact the manufacturer, even though it does state Cricket Wireless software update.
