For some reason, all the links that are appearing in one instance doesn't appear in other instance. All this is happening with just one instance and it used to display all the links before. All the custom links suddenly disappeared without any configuration changes.
Is this a bug with Jira Cloud? or it has to do with some configuration settings?
Unfortunately cannot reach out to Atlassian support team as this is on a free plan.
