Sorry, no sympathy for officials, when they make decisions with less than 24 hours to go.. I'm somewhat surprised at your position, considering you are so affected by this.
Every 24 hours brings new infection numbers, it's still an evolving situation that makes planning difficult for everyone.
And I will admit that I was angry and frustrated when I first found out. It's been easier to be understanding once I had an alternative (charter flight) in place.
I just don't think the last minute change is capricious or shows that they just don't care how it affects travelers and the population.
