This issue was present on Sequoia and 26.0 and the 26.1 beta. I am on the latest BD version. For some the auto brightness does not want to work. I've tried toggling the Mac auto brightness on/off but that doesn't help either. I've tried to disable the BD auto brightness and rely on the Mac version, and vice versa, and nothing works. Any ideas how to get that to work? I am at 92% brightness and I went from a fully lit up room to a dark room and it didn't budge. I feel like I am missing something I just don't know what. Any help would be appreciated. This is MacBook Pro 16in M3 Max.
