I just added and set up an ad to start on 1st January and it just went online instantly.
I haven’t scheduled a start date for an ad before only an end date, and that still appears to work since updating to 3.10.17.

I have the same problem if the ads have margins added. Without margin they stay in the same row, but obviously back to back.
Even worse than the size-issue:
I’m not able to add a new group/ad via the widget. It says, “Error, no Ad ID set! Check your syntax!” even though I have typed it.
I have the exact same problem.
But it appears that the problem only occurs, when a group is shown as a block of ads (number of ads doesn’t matter).
