Our Team's Sprint starts from Tue of 1st week and ends on Monday of 3rd week. It is a 2 weeks sprint. If I want to find out issues logged in the last 14 days - how can I find that? Just like we are able to find bugs logged in last 'n' hours, can we find bugs logged for last 14 days?

How to find issues that are assignee changed by more than once.
