I updated my NVR from V4.4.015 to V4.60.005 yesterday and it only remembered half the details on re-boot. I had to re enter all hik-connect details, alert email addresses and camera intrusion detector parameters etc. V4.60 is dated 07/03/2023 so not that old really. I would try and find out what's been rolled out in the update, see if it's worth the risk.
