This is the 2nd time I've ever installed a beta on either an iPhone (xr), watch(5), or iMac (2019 retina), and I must say that I am very satisfied with this risky step.

Just for info, all apps work for me on all 3 devices as before. In the app home I can't find the setting on adaptive lightning, but that is probably a matter of the bulb manufacturer.
I will add that all 3 devices work faster, the operating systems are more beautiful, cooler, more refined and faster.
I wouldn't say the new system is faster https://www.youtube.com/watch?v=Fvig5aGX-gs&t=473s.
