We are experiencing this error with Telerik Reporting version 12.2.18.912:
https://feedback.telerik.com/reporting/1413307-error-handling-on-finishing-of-the-report-rendering
If I hover over the "Completed" tag, it says, "Implemented. Refer to the item for information about the release this is included in." Where can I find the information about how and when the error was fixed?
