Same. Not only adaptive brightness, but the brightness slider -- I use one of my phones exclusively with the navigation app, and I had the profile with the app set always to 100% brightness (and then some with Adaptive).
Worked wonderfully well in all conditions.
Now pretty much always when I login to the profile, I have the brightness set to 50% or so. Once I noticed it to reset the brightness I set to max back to 50% when I put it on the wireless charger.
Maddening :(
