We know there was an unintended delay in the start of the deliveries, so clearly Jolla is pushing their 3-4 week window into "spare time" so to speak. There is some reason to worry for those still in Paid, schedule-wise. Hopefully not much.

I believe that for most people, 4 weeks comes up this week - if it hasn't already. For most of the rest by or during the Christmas break, so Jolla needs to deliver by Christmas to stick to that.

For someone paid December 2nd, they have a couple of days after Christmas to deliver, but this is probably a quite small minority - mostly those who didn't get the webstore invites in their right time (which kind of should have made Jolla prioritize them a little more).
