New software id

Hi,
I’ve got a problem with sotfware id code.
Some of my Router OS after being restarted gets
new 8 alphanumeric Software-ID
Old software id:
6Z7U-LTT
New software ID:
ND9P-JQC0
Previously new software id:
ZUJF-23T7
Is this normal ? I am using this to identify devices on network.

make sure to upgrade RouterOS and the Bootloader Firmware to avoid this kind of problem

HI,

I am also facing this issue. I upgraded my ROS to 3.28 and since then i am facing this…

facing what? do you mean that when running v3.28, after each restart you get a different SoftID? clarify please
