These tickets were not extended, they were purchased as part of the free dining recovery offer that was later converted to a room discount. We had active APs at the time of our July trip and were going to try to bridge the 2 day tickets to a new AP or use them towards a future trip.Tickets for July 2020? Check MDE - most tickets impacted by the closure were extended through 9/26/2021. Yours may be included in that extension, offhand I don't recall the specific dates that got the extension. If your tickets were not extended, you should be able to upgrade them to new tickets over the phone.
I will call WDW sometime this week and post the results here.
