I like how easy it makes reporting our status to stakeholders or partners who aren't part of your team using an app - no more emailing screenshots! Having all this information in one place helps us prioritize projects as well because we can see what's going wrong with each other easily (and also give feedback).
It could use some UI/UX improvements but overall its been good for tracking issues between multiple teams which was previously not so simple since emails were scattered among different people across various time zones etc., We now have clear visibility over where everyone else stands when there're deadlines looming next week / month ahead instead of guessing from their respective schedules posted online via slack channels every day during business hours :D.
