My Control Centre is a bit different. I have:
• Airline mode
• Do not disturb
• This will be either "Rotation lock" or "Mute" depending on what is selected in Settings/General…
If Mute is selected in Settings/General, then the Control Centre icon will be Rotation Lock, and vice-versa, which means I cannot have both Unmuted and Unlocked Rotation.
And, of course, there is still the matter of the instruction in Settings/General to "Use Side (sic) Switch to: " but without providing Slide Switches.
I'll give the reboot a shot.EDIT: Nope, reboot didn't do it. I can have "Mute and Free rotating screen" or "Unmute and Locked Screen" but not "Unmute and Free rotating screen".EDIT AGAIN: Well, I found this link also referring to a Side Switch (where I had thought Side was a mis-spelling of Slide) and, after a bit of goofing around, have things working. The "Side switch" (on the "side" of the machine) was in the lock screen mode. Now that it's moved, I have everything.
Would it be better if I have a nap before logging in?
