How can remove a link from an issue using atlassian-python-api?
I have a list of issues, I get them using jql, I want to delete a linktype from all these issues and add a new one.
Work flow:

  1. jql = “issueFunction in linkedIssuesOf("key=ABBA-1100 and project= NNNN")”
  2. remove all links from jql with link name = “is tested by”
  3. add link to all jql with link name = “is tested by” and key = ABA-25200

Thanks,
julio
