What could also help is to check the departures of Easyjet from your airport. I can see my flight to Rhodes is not on the departure list for the 4th of July, just like the other zero'd out flights. Then from the 18th of July the Amsterdam Schiphol Airport app shows an Easyjet flight to Rhodes again, which corresponds with the bookable flights on Easyjet.com. Everything before 18th of July is zero'd out.

I am 99% sure my flight gets cancelled.
