Some worklogs does not appear on the Reports and Issues

When you experience that only for some users or Issues worklogs do not appear in the reports and on the Issue view, it is possible that these worklogs are not properly indexed and our app is unable to query them.

You can validate if this is the case by simply searching for these Issues with the following JQL:

If the Issue(s) does not appear running this (or similar) JQL where there are existing worklogs, then it is the result of Atlassian added safe guards to the indexes for worklogs.

To resolve this, this documentation linked below and adjust the default value of a 100 to a bigger number (eg. 1000): How to change Indexing Limit Safeguards in Jira | Jira and Jira Service Management | Atlassian Support”

Note that, excessively increasing these limits can have performance implications, especially if many issues exceed the default values. Atlassian recommend testing these changes in your staging environment first and try to find a balanced value.
