When the toggle switch is “on” - if a field can’t be updated in a Jira project, you can’t edit it in BigPicture column views and cards.
For example, when you try to edit a task value in BigPicture, the app tries to find a matching Jira issue field in a project. When the field doesn’t exist (that issue doesn’t have it), the app doesn’t let you edit the field.
Settings can be adjusted per Jira project, just like other field mapping settings.
Note: restriction doesn’t apply to fields that have been mapped.
