I´ve been looking for documentation regarding license expiration notifications. I´m pretty sure that the first email is sent to the dashboard admin on the 90s day before expiration but I´m not able to find any documentation on the notification process.
90, 60, 30, 0 and the 30 days grace. After that the network doesn´t push any data.
If you have any documentation supporting this I would be happy to get hold of it.
