So basically my initial email was product.lead and i created my own dahsboard and team within the company Jira, After 1 month they changed the display name of that email to myname@companyname.com instead. It was smooth sailing and can still use and add tickets until yesterday when they changed my profile to the new email myname@companyname.com instead hence i got no credentials.
Please bare in mind that the initial email and the current one is the same email just changing of display name. But why i no longer have the authorization on my board.
