Missing display / toggle for adaptive brightness in windows update 1809

Not sure WHAT is going on but 1809 issue with adaptive brightness and that the brightness will NOT change between battery and plugged in WAS FIXED in an Update last December to early January depending on your system.

I had the EXACT same issue and it was resolved.

NOW in June 2019 the 1903 came - on HP Envy running Windows 10 - and the adaptive brightness is GONE again and the issue of battery v plugged in is back again. SO ANNOYING. Sent numerous Feedback Hub reports but that really is useless.

Really weird that if you click on battery on task bar and open up settings I get this message:

YES it is set to 100% on battery BUT IF I change it to 80% which is what I want it ALL I get is this message and then I have to manually change it back and worth - REALLY ANNOYING

CAN SOMEONE PLEASE THEM TO FIX THIS

This forum is made up of just users not Microsoft support.

This issue is driving me crazy, the brightness is always too dim and there's nothing I can do to solve it. The option on my Asus VivoBook X510U is also missing(it's in Portuguese, but it's possible to see there's only one option under the Video item). Is it a known bug or we're facing some sort of error on out updates?

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.

This whole thread should is painful to read and should be an embarrassment to Microsoft.  I get so tired of reading these threads where MS has no idea what people are talking about and act like they have no idea there is an issue when users are clearly explaining the problem.  It is also pathetic the support doesn't know what an Acer Swift is, or cant do a little homework to find out so they at least appear that they know what they're doing.  This adaptive brightness thing is a blatantly obvious oversight by Microsoft and is why I wont update my laptops to 1809.  Stop treating your users this way and fix this stupid screw up.
