I am so sorry about Content Scheduler’s current state, but I have some good news. I recently have been out of work, so I had time to fix things in CS. I am quite literally finishing Multisite support in it today, and should have an update pushed this afternoon.
CS had some problems mainly with timezones, a difficult-to-reproduce wp-cron issue, and Multisite. I think I’ve been able to fix them all. Check this afternoon / evening for an update. I hope to keep on top of this and add other plugins in the coming months.
