Alright guys, I just finished some changes that will fix the AOD/Ambient Display issue. There was a missing commit, even LOS doesn't have it as far as I can tell, that added the Always On Display switch to the Ambient Display screen in Settings. I now have that option added, and tested as working on cheeseburger. However, the change is strictly to the common tree that cheeseburger and dumpling share, so it should work the same on dumpling. I have pushed the change up, but I am waiting to see if anyone else wants to test before the change goes live, so it may be a day or two before you see a new build with the fix in it. I am attaching a screenshot of the new Ambient Display options screen from my cheeseburger device.
