I installed the Google Family Link app (child version) on my Nokia 7.1 and configured it with my Google Families account as a child account. As soon as I did, though, the phone changed the time to one hour ahead of what it should be. After checking the time settings (which are all greyed out), I saw that the timezone was set to GMT-5. My timezone is GMT-6 which I previously had set on the device but was now changed by installing Google Family Link. I previously had to set the timezone because there is no SIM card and no cellular network provider providing the time to the device.
My assumption is the fact that there is no SIM card is affecting how the Nokia device sets the time when it goes under device administration.
I've contacted Google Family Link support and they haven't been much help.
Can anyone else confirm this same behaviour? Any suggestions?
