@apps How do you distinguish between "Post is missing from the timeline because the server didn't include it" and "Post is missing from the timeline because the original author deleted it"?

To put it another way, is the app inadvertently showing posts that have been deleted by the original author?

Same question, but for edits. If you cache a post in the timeline at version 1, and it's subsequently edited to version 2, does the app show version 1?
