I am sorry, but I am not entirely sure if this should better be an enhancement. But e.g. Worklog Calendar is not working for me.
The Jira Cloud instance contains a very large project. And the JQL used for fetching worklogs fails with Internal Server Error 500.
JQL used for Worklog Calendar looks like
worklogAuthor in (currentUser()) and worklogDate >= '2023-10-08' and worklogDate < '2023-10-17'.
When using the query console in Jira itself it results in the same error. But it is quite easy to compensate for this by adding
Please add functionality to customize worklog JQL.
