Because it's a Special Use Airspace. (Not a very good idea to fly with any aircraft in that area)Why when in R-4006 controlled airspace in Heathsville, VA with a restriction of 3500’ and up do many apps I look at show it as a no fly zone?
Fully understand where and what R-4006 is. The floor of R-4006 is 3,500 ft, so from 0 to 3,4999 ft is not in R-4006.The sectionals show that area as SUA:

Commercial and recreational UAS pilots: restricted and prohibited areas, active temporary flight restrictions (TFRs), and the Washington, DC Flight Restriction Zone (FRZ) are shown in red. UAV flights are not allowed in these areas without explicit permission.
Never looked at it that way, I guess all areas are marked and you have to look at the area details to see if the restriction applies to your flight. It seems the DJI app would not give you the warning since the altitude is considerably higher than the legal flight limits. Thank you for the info.Fully understand where and what R-4006 is.
