I'm a Jira user using my personal credentials provided by my company. I installed the Jira app on my iPhone but was not able to log on via my email address as I only log on with my username. So I created an account based on my email address, but is's not automatically linked to my account provided by my company. Do I have to delete my newly created account? Or can i Link both accounts so I can use the app logging on with my email address?
