But I did not manage to replicate data monitoring failure. Could you provide exact steps how to reproduce the issue?
After setting up the device with my settings everything works, after switching the modem from IPv4 to IPv4/IPv6 statistics stop upgrading.
Also, did you perform firmware update with Keep settings option set to on?
Could you reset your device to factory defaults and try again?
Already tried factory reset, then installed backup.
Have you tried if a simple logging out and logging in or device reboot helps to mitigate the issue and monitor data consumption with IPv4/IPv6 set?
