For me when it comes to full use, peeing is a non issue and always has been.
As for messing I used to do it in my pants a lot as a younger boy before I could get nappies and subsequently (so as not to have them discovered) I would have to empty and hand wash them before hiding them away to dry before putting them in the laundry. Not a pleasant task but something I accepted as part of wanting to poop myself, after a while it stopped being a concern so when I was able to start getting nappies whenever I wanted messing them was not a problem for me (actually a lot easier to clean and deal with than going in my pants).
The only time I ever had/have hold ups about pooping is when I knew there were other people in the house who might smell it especially right after I've had a change/clean up.
Now the interesting part is that I believe I do know exactly what you are talking about when you say...

recently I find that my body just decides to when I’m in one whether that be 1 or 2.
I posted about this before a few years back. Longish story but for some background...
While I have worn 24/7, full use, for prolonged periods before (longest being 4 months) I used to wear regularly but intermittently, there have been times where I don't wear any nappies, sometimes for several days or even for a few weeks and then periods of 1-3 a day or 1 every other day etc. It used to be that most of the time I will only wet because I don't live alone and don't want to stink the house out so I'd poop in the toilet before putting one on or wait till I took it off.
I tended to plan my messy nappies for when I was going to be alone and would have time and space to clean up and air the room out.
The last 5-6 years however I have been wearing much more often with shorter and less periods where I don't wear any at all.
I still tend to plan out when I am going to have a messy one in advance however, If I do happen to have a nappy on, even when I have not been thinking about messing in it, if I need to go I will generally just let it happen and then get changed fairly quickly.
It's very rare I poop in the toilet at work and I walk home so generally when I get home and sit down to chill out I usually feel the need for a bowel movement within about 30 minutes. I don't wear nappies to work (except the time I went 24/7 for 4 months last year) so I'll usually still be wearing my underpants unless I'm planning a padded night and change straight away.
Now a couple years back I began noticing a trend in my bowels wherein after getting home and starting to relax, I'd feel that need to poop and it didn't matter if I was wearing pants or a nappy or even if I was planning to put a nappy on later or not my body would seem to just ignore any instructions to hold it.
Like literally there was no attempt made by my body to clench up and keep it in till I could get to a toilet even with me sitting there thinking "no no no no I don't want to poop myself right now, keep it in, keep it in". It was like my brain was in conflict... a conscious part thinking no don't do it, I don't want this and a subconscious part thinking this is going to happen, don't fight it, and the muscles would listen to the subconscious part and relax even more.
It was almost how I'd expect actual incontinence to feel, not wanting the movement to happen but being powerless to stop it. The thing is I know I could have stopped it anytime if I had really wanted to, but a part of me actually kinda enjoyed the feeling and that subconscious part of the brain knew it and was able to take control.
9 times out of 10 this would leave me in messy pants and running straight to the toilet to clean up feeling kinda sheepish where if I had planned to do it I might have sat in it for a little bit afterwards contentedly. This went on for several months before dwindling, still happens sometimes but not that often.
