When will be the next update to fix the problem of missing the toggle to turn off the adaptive brightness in windows update 1809? This is a big issue for me in work. Waiting for your immediate answer.
I am Using Windows 10 64 bit and currently updated to build 1809 (latest)
Laptop: Acer Swift 3
Thank You!
I also noticed that the adaptive brightness option is gone on my asus vivobook s after the 1809 update.
Also faced a strange issue, the brightness of the screen once suddenly became too low even at 100%. But it got back to normal after a restart. Haven't ever faced such issue on the earlier build.

Is your problem solved now? Because I'm facing the same issue with my laptop which I have bought just 4 days ago.
Any help would be highly appreciated.
