How do I populate Global ID?

[JustinOdell]

I created a File Geodatabase containing a feature class with a few thousand features some time ago. I forget exactly how I did it, but somehow I managed to calculate a Global ID for all the features.

Now I am editing the feature class and when I create a new feature the Global ID is not populating. I have tried various methods, but can't get it to work. Any ideas why?

Ah, think this is how I did it:

How To: Calculate unique identifier values similar to Global IDs 

However, I am now getting lower-case Global ID characters whereas before I was getting upper-case. Not sure if this has anything to do with a version upgrade from 10.3.1 to 10.7.1?
