I have 3 separate applications that have no relation/interaction at all. Each application has it's own team of developers and release schedules. I have these set up as separate projects; however, I have run into a snag whereas I can only have 1 sprint active at a time. Therefore Project A's sprint is started and showing up in Project B's queue and does not allow me to start a sprint for Project B. Our release schedules run in parallel so it's important that we have the ability to have multiple independent sprints running simultaneously. How can I achieve this result? I'm currently using the Bug Tracking option and the Scrum project options. Any advice / help you can offer is greatly appreciated.
