Around thanksgiving user reported that JIRA agile Scrum Board do not refresh when sorting by a specific Sprint, unless hitting refresh on the browser.
We are running JIRA 7.3.3
It is also noted this is not just happening on Chrome, Firefox was used as well.
Another thing to note is that once user is in the board, they get a notification of something changing in the board and user should refresh or do nothing in the bottom right corner, refreshing again will go to all sprint view even though the specific sprint is still selected in the UI as well as in the URL.
