Sometimes it happens that the custom field in classic projects was not created automatically. If you can’t find the custom field “Linked assets”, you can create it on your own following these steps:

  1. Got to Jira > Jira settings > Issues > Custom fields

  3. Give the custom field an arbitrary name, e.g. “Linked assets”

  4. Click Create
