We have a Scrum (next-gen) project in Jira, that uses a new view mode of the issues. One of the features of this view mode is to show whether the issue is a child issue of an Epic and the ability to add or change the Epic/parent.
You can Add/Change the Epic through the bread crumb path at the top of the issue view, or from the Change parent menu item.
But when Jira sends emails regarding changes to an issue, the issue link has these extra parameters: ?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel.
This causes the issue to be shown in a different (old) view mode that does not show or give option to set Change parent or Epic. There are several other differences between these views as well. Simply removing the parameters from the browser's address bar and reloading the page, fixes the issue by bringing the correct new type of view.
The parameters does not seem to serve any purpose.
