So today suddenly out of the blue my Mavic Pro says “NFZ.”

I"m looking at the UAV Forecast App and yes there appears to be a big heliport? surrounding me.

I’ve been flying in this location for 8 months with no problem. I am near, but not in the Gettysburg National Military Park. There are no TFRs listed for today in my state, Pennsylvania.

This is a very rural area. The heliport which I guess exists must be basically unused.

What to do?

Thank you.
