Has anyone had this issue? Here is what happens.
New dashboard. I can add the gadget with no issues. I edit it to set up the filters for 5 different projects, filter by Username and set a date for "is after" with a date. Then I set the Jira filter for comments, issue edits, issue progress started and issue transition. Then all entries show perfectly fine with accurate data. Refresh the page and the gadget goes inoperative showing "Service Temporarily Unavailable". I can delete the gadget, re-add it, all is well again until I refresh the page.
Chrome version 75.0.3770.100 (Official Build) (64-bit)
