Recently I have noticed a general increase in latency in the Identify modal before Reviewed status gets applied. Not huge, but noticeable. Even when the graying first shows up, if I then refresh the modal with the browser, the last observation IDed still shows up unreviewed. But after a second refresh, it doesn’t. Eventually everything that should be marked as reviewed seems to show up that way. Very occasionally, if I arrow away to the next observation too quickly (like, milliseconds quick), it may not get marked at all.
So I’m thinking variations in people’s workflow speeds and connection speeds might account for some or all of the inconsistencies noted in this topic.
