Yes. I don't know what you mean by "reversible transaction" but I published a post today, saw it for 3-4 seconds on my own feed, but when I reloaded it disappeared. For me it means it wasn't on the "last reversible block".
Yeah, I've heard this story too. But for all I know, it's entirely a UI bug. I have no evidence that these transactions ever got accepted by a node, then "lost." But I could be wrong.
