@digitalcuriosity "I feel Apple needs to have a user manual like many companies had years ago..."
I fit into the OP's target age, but my cognitive decline is not yet terminal.

I get by using about 5% of my iPhone 13 mini's features, because I haven't been able to RTFM. 😱
If there was a pdf (indexed) manual, by the time Apple writers get it finished they would have to throw it away and rewrite another one. 😯
Online search isn't 'a good alternative', because the answer doesn't come with any cognitive context so is just another random thing that has to be memorised.
One thing I do have expertise in is Apple's Final Cut Pro (for Mac, not iPadOS haha). Using Premiere and FCP<7 was my job for two decades.
It has a ~950 page manual, which I've read and fully understand.
But which I no longer have the power to memorise fully.
There are about 550 documented keyboard commands, which are listed in the manual.
There are a not-fully-documented proportion of these commands that the Undo key will work on.
If you use Undo on a command that doesn't allow it's use, then the program will 'undo' the last command you used that does Undo...
With no indication on the user interface if that section of the project isn't visible.
So to use the program fully you have to have read and memorise the whole thing, because very often the actual user interface isn't giving any clue as to what you have just done.
And you can wreak havoc on hours of previous work...
I don't use iPhone third party apps except WhatsApp and FB, and the NHS (govt Health app, which is essential!), because everything important is done on my desktop 5K Mac, which has multiple 'spaces' to lay out all the information I need - where it can exist without risk of losing it...
I'm very certain I won't be able to memorise the whole of any particular iteration of iOS, so I get by at about 15% of the speed you young Bro's manage haha.
Would that it were different!

So you start understanding things have changed and if you want or need to deal with any of the above you have to find ways for doing it."
Good God! One comma, one capitalisation and one Return...
I can't learn to use iOS like that. 😱
