iOS Analytics and Improvements - Enabled or Disabled?

[Helmsley]

As per the title of this thread, do you have iOS analytics and improvements enabled or disabled on your device(s).

I've always had it disabled but I doubt having it on causes any issues

I have it all off except for “Improve Fitness+.” Seems innocuous enough and it’s a newer service that I use quite a bit and that I would like to see improve.
