Hi,
We manage NF from a Mac (OS X 10.9.5, Chrome 37.0.2062.124), the parent computer, and use it on children's Lenovo (Windows 8, Latest Chrome and Firefox). There is a very long delay (2 - 24 hours) between an event on children's computer and the report in the email.
We tested the feature by logging-in under children's accounts, visiting forbidden websites and leaving emails to "parents". The websites were blocked, but the notifications only arrived on the next day, rendering the whole feature almost completely useless - children can't request access and wait for a day until they can visit a website.
Looks like a similar problem has occurred multiple times before - if you Google NF notification delay, there are many reports from people who also had this issue. Could you please advise us, how to address it?
Thanks!
