Issues with smart invert


A friend's 8+ upgraded from iOS 12 a couple of days ago in spite of having all updates turned off. She has depended on these features, and they have worked out quite well. After the upgrade however, Invert seems to be disabled each time she goes into another app. She then has to turn it off and back on. It then stays on until she goes to another app which requires her to repeat the steps. The behavior is the same if dark mode is on or off. Any ideas? Has anyone else seen this? Thanks
