A friend of mine participated in the free play period at the end of June. Her last day of actual subscription was in February. How does this interact with the callback campaign? Is the requirement of 90 days counted from the end of the free play period or the last actual subscription? If it's the end of the free play period, how exactly is it counted? If I'm right the free play period ended on July 2nd at 0:00 GMT, so 90 days have passed on September 30th 0:00 GMT. The callback campaign is in effect until September 30th 8:00 GMT. Does this mean there's an 8-hour window for me to send the invite and her to accept it? It's a bit tight, but I think we can make it if necessary. Is there any harm in trying earlier, to see if the free play period doesn't count against this?

I feel like it would be polite from SE to not shaft players who participated in the earlier free play period, because the callback campaign is clearly a much better deal and back in June we didn't know it would be coming.
