I just created a Jira cloud instance to explore Jira and its features. I created one team managed Scrum project in JIRA and imported some issues using .csv. It all worked well and I can see the items in the project.
I am trying to update story point (using Story Point Estimate field) in the Backlog view and it says "Failed to update" -The items may not be editable.
I created a new item using Create button and added User story Estimates and it says
"Field 'customfield_10016' cannot be set. It is not on the appropriate screen, or unknown.".
I can see the Story point Estimate field but it is not letting be edit in already created items and not even letting me create a new item with story points.
