In JIRA CLOUD, how do I clear the resolution when re-opening an issue?

[Simon Jacobson]

In server I use a post-function. I cannot find any way of doing this in cloud. It is an issue now on my project.

Found it after too much fruitless googling:

1. Click on a transition arrow after it has been created
2. Post function category now visible
