Hello Atlassian Community!
I would like to know how you can update the Cf values ​​in the “description” field without losing the task description itself inside?
I've looked at the intellectual value, but I don't fully understand how to use it.

I have:
1. Automation .Issue created . Where field "CPU" copying the field to the description

and

2. Automation. Field changed(doesn't work well)

Your help is greatly needed!

Thanks!
