Please also confirm which country you are in, as the 500m height limit is likely region based, but could now be worldwide, and we therefore need to segregate our testing results by country. Hopefully, in the U.S. it is still 1000m.
On the DJI forum someone indicated that after this update their altitude limit was max 500m. These things are often region based, their country was listed as New Zealand. Just an FYI for anyone thinking of updating.
