Hello Jason
I’m glad to hear that you found the previous information helpful!
Concerning your question about the RTU license, if it shows Period left: Life time, it means that the license is permanent. It won’t expire and you can use the features associated with this license indefinitely on your device.
In this particular case, the adventerprise feature is under the RTU license, which means you can use the advanced enterprise features for the lifetime of the device.
Just remember, while the license is active and in use, it is not counted against any usage count, hence you see License Count: Non-Counted under License Count:.
I hope this has been helpful!
