We just setup our first clickup project (newbies) which was quite large with many dependencies. When we tested moving a key dependency, we realized we'd made a couple of dependency errors that we'd need to fix. However, when we tried to track down the original state of some of the tasks that hadn't adjusted as expected in order to identify the initial amount of time between the task and the one it should have been dependent on, we realized that the system had not recorded the (48) task state changes that clickbot had made, whereas the system had recorded every state change our team had made.
Fortunately, we backed up the space prior to executing the test but we feel it would be incredibly helpful if automatic updates were recorded and viewable in task history. That being said, we're loving clickup so far.
