Not measuring correctly w iPhone 11 Pro – Dark Sky Meter Review

I used this app for years in my backyard with an iPhone 6 Plus, getting readings between 19.35 and 19.5 which seemed to agree with what was visible in the sky. Since getting an iPhone 11 Pro I get readings around 17.30. The light in my backyard did not change that much in a week. Update 12/28/21: After getting the update I was back to readings around 19.5. I received an actual SQM meter as a Christmas gift. It shows a reading of 18.44. So while the app is back to its old readings they appear to be on the optimistic side.
