Sorry for not responding sooner. Easter had me overseas and rather unavailable. It does seem to be a future publishing issue. This always used to work (I'm pretty sure??), so will have to see what has changed there. I got the last two notifications, so guessing the post you posted most recently was also just immediately published?
They should both work of course!
Write, save as draft, re-open, publish with a future live date, go back in and re-edit, with the same future live date publish.
I am pretty much sure this is now fixed Greg. Interestingly enough, this probably has never worked Basically, the Edit page wasn't set up to handle edits of already published entries very well, specifically when it came to subscribers. So the second edit was switching off subscriptions. I guess it's pretty rare or we would probably have heard of it more!
Anyway, let me know if you see this again, or see some other bug related to it!!
