“Such and such works fine for me” Ok? That’s nice but useless—unless you can offer any input that might get such and such working for whom it isn’t.
Aside from running iOS on a jailbroken and/or ancient device, and aside from the occasional slip-up, there is virtually no excuse for most basic things to go awry given Apple’s obsessive, granular, end-to-end control over essentially every aspect of its hardware and software and careful oversight of the App Store approval process.
Even if something goes wrong for one user among billions it should suffice to raise red flags because as much as fanboys love to excuse Apple’s missteps (especially as of late) all it does is enable such sloppiness and laziness down the road in greater numbers.
Start putting Apple on blast and stop trying to gaslight the end user into going through a convoluted restore process or filing bug reports that clearly have been falling on deaf ears for some time now.
Also, if the over-the-air update process were the primary source of Apple’s declining software quality, surely they would have taken the time and steps to address it, but instead OTA installation continues to be regarded by Apple and the majority of users as the simplest and therefore the most logical way, the way that requires just one device and “just works.” And work it has, at least for said majority; I’d wager that the essence of the software being updated is the problem.
In such a walled, manicured garden it can’t possibly be “user error” 99% of the time. It’s Apple’s error.
