Hello. I use webnovel app on both iphone 8 and ipad pro. Brightness regulator is not working on both devices. I also tried it on an iphone 6S, ipad mini and ipad air. Still does not work/ That's why I came to the conclusion that it does not work on iOS devies. I hope you can do something about it. Thank you and have a good day.!
