iOS Problems?

so I'm a completely blind iPhone user and have been for like 12 years. I lost my complete eyesight in 2015 but before that could see just fine. I'm just saying that before I explain what I'm about to get into here.
so around 9:40 PM tonight central standard time I get a notification saying private relay is no longer active. I go to the setting and it's still on but there's a notification at the bottom that says it's temporarily not working. Any reason for why this could be?
Secondly, over the past couple of years iOS updates have affected the quality of using my iPhone as a blind user. For example, in the Notes app, let's say I spelled the word "like" for whatever reason let's say I delete the "i" and type it in again, the phone will pronounce the word differently in a more broken up structure. When I back out of that note and go back into it, it will read like normal, but this has been a problem for a couple of years now. it's annoying.
The next issue I've experienced is in the Files app, specifically when opening videos, the buttons for clicking done aren't always on screen, and in my case, I've had to turn off my voiceover temporarily double tap the video turn voiceover back on and sometimes that works then I can click the done button or other times. I just have to tap around in the corners until the video closes.
Other weird things that have been happening. Lately is my screen curtain, which is a feature when voiceover is on to make the screen go black because I don't need it to be on so it's a waste of battery, has been glitching, turning on and off rapidly at times. My phone announces this and it's very strange. This has been happening over the last few months.
Lastly, it used to be that I could turn on my voiceover before entering the phone passcode during a restart. There are times where my voiceover might be off for whatever reason the phone dies. I get it back on. I turn on voiceover and then I can type in my passcode and get back to Business. Now, if my phone dies or power is off while voiceover is off, I can't turn voiceover back on before I enter my passcode. this is actually caused massive problems for me in tight situations where I was essentially stuck not being able to get into my phone until I had somebody with eyes that could help me. In my case, since I live alone, this has happened a few times. On several occasions there were hours of me just not being able to use my phone and I couldn't contact anybody. Sometimes I can work around this by having a secondary phone with B, my eyes installed, but it's an older iPhone XR that's not in the best shape and it's not always with me.
I say all this to say, what's been going on with iOS and why has the quality of its updates been going downhill? Also, does anybody with program/software experience know why some of these issues might be occurring?
Quality of using my phone was at its peak when I had a perfectly working iPhone XR and over the last two years or so apps have just had these weird glitches, and the experience hasn't been so pleasant. 😔
