Animal Kingdom Refurbishments Timeline?

I noticed that Fastpasses were not allowed for Flights of Wonder in Animal Kingdom on March 21 through My Disney Experiences. However, the refurbishments for that show and the Boneyard are supposedly completed March 17. So are they just being cautious or are they further delayed?

I wasn’t planning on Fastpassing Flights, but hoped it would be open. And I will be very sore if the Boneyard is closed- that is my kids’ absolute favorite playground and where we like to spend the afternoon. Grrrrr.
