How can the results of a drawing be selected when it falls after the date of the convention?

Winners would be chosen before Blizzcon, on October 1. They contact winners within a week of the drawing. So all winners would be notified ahead of Blizzcon. A winners list is what is posted in November. Winner's lists are not how they notify winners.

I'm not sure which sweepstakes you're referring to, but if you can pull it up, check the official rules for when the drawing is. They notify winners approximately a week or so after the drawing and the drawing can take place weeks after the sweepstakes ends. They don't post a winner's list until all winners have been notified and verified so a list is usually not available until about a month after the drawing.

When you click a sweepstakes to redeem tickets for it, before you redeem the tickets you can scroll down through the information for the sweepstakes and it gives the end date and a link to the official rules which states when the drawing will take place for that sweepstakes. Winners are typically notified within 1 week of the drawing.

It is also appearing for me. It freezes sometimes after selecting the song or at the end of the song when the summary with percentage result should be displayed. Please advice how to get rid of that issue.

Oh, I see. So this is through Microsoft rewards. I believe they have a set date for the announcement on the winners for this. But the draw has already ended. I would suggest just to wait for an update for the announcement on the winners as it will just be updated in time. Most of the time they will announce winners within 7 days after the last draw date.
