Fortunately, its installation on both my iPhone (16) and Mini M2 asked if I wanted to initiate it, or wait till later. Chose later in both cases. Waiting to see the inevitable sh*t hit the fan first, as users deal with it. Reports read from earlier Betas didn't really entice, either. Well that, and I can't honestly see the point behind it, for what I need / want my devices to do.

About the only thing I've done on my iPhone is return my Mail view to Lists from Categories.
