It seems like several of our company's employees machines are not properly sending a heartbeat to avast, because when I see their computers in the "Devices" area, it shows several weeks in the past.
It also appears to happen on my computer, where I can see that:
1. After a restart, it *does* update the "Last seen" time.
2. Some amount of time after the restart (maybe associated to a network configuration change caused by VPN software?) the "Last seen" timestamp won't update anymore.
So my questions are twofold:
1. What is this "last seen" timestamp supposed to represent, and is it not working for this case?
2. If it isn't working for this case, what do I do to fix it?
