On a notification mails there is a link to the ticket like  https://domainname/ChangeDetails.do?CHANGEID=4115 and its working fine but sometimes on some users (not on all users) its leading to the  https://domainname/HomePage.do?SkipNV2Filter=true&CHANGEID=4115 when click it and opening the homepage not ticket. Last week we upgraded to the 9213 and there was not a problem like that before upgrade.

Do you have any clue?
