The "linked issue" doesn't work in Clone issue

• what version of Jira are you using: Cloud, Server, or Data Center
  

  Jira v10.3.8

  alm-jira.systems.uk.hsbc
• images of any relevant trigger / actions / conditions / branches

• explain what is not working as expected and why you believe that to be the case
  I explicitly set the Linked Issues "field" in the Clone action to link the cloned issue as "is supply ticket for" for "trigger issue". But nothing happened.
  The Clone Issue add a cloned link between 2 issues, but it's not what I need.
  The cloned issue is in APICLOUD project, different from the trigger issue which is in SPCOELAB project.

Hello @flourish_x_yang 

Clone issue is not a true Jira clone. Atlassian explicitly says that this action creates a new issue, the cloned issue is not linked to the original issue, and due to API limitations it does not clone issue links. That is different from the normal Jira UI clone flow, where the original and cloned issues are linked.

You posted a screenshot, but you did not explain what you want to achieve.
