Same is happening for me. It periodically disconnects or just stops posting my scheduled posts and does not even give an error message all the time (sometimes it will say your scheduled post was not published, please try again, and other times it just doesn't post it).
It looks like there's a lot of glitches with this new feature.
Currently, I have posts scheduled for the rest of the month, but this morning there was no post. I go online to check and my account has been disconnected and it is not letting me successfully reconnect....
Very frustrating. I called customer service last time something like this happened and they essentially just said they will file a ticket and let the developers (or whatever) know about this issue.
