@david2 Yes it’s a problem that seems to be separate from the ‘Parent link’ outage from yesterday.
The documentation mentioned by @sunnyape says that Atlassian will start removing Epic links from the UI and partly from JQL in 2023 but the corresponding developer notice explicitly says that JQL changes are out of scope:
Will Epic Link or Parent Link be removed from JQL?
No. Also, we will add full company-managed project support to the
parent
JQL, and it will become the recommended way of searching for issue’s children in JQL. Read our Community announcement about it .Note that all changes to JQL (including the full support for
parent
JQL) are out of the scope of this notice and will be released separately.
@sunnyape I’d love to have access to the instances to answer the questions 2-3 JQL without epic link works fine.
