This bothers me too, especially with people who been playing for years. And baffling too, as these are really smart people (if I have to explain how to calculate spell save dc one more time...).
But then I wonder, maybe it's not the players fault, but the game's (hate is too strong a word...). Some players just don't care about the rules. The flip side to this is that they also don't care if they do something suboptimal (like forgetting to add their proficiency bonus). It's what got me interested in rules lite games.
There's also the question of finding the right tools. When the pandemic started I was dming and tried to switch to roll 20, but I found there was just too much cognitive load between finding images and maps on roll 20, paying attention to the players and my own notes and tabs I had open, not to mention various technical problems that come up. This post describes it as "creeping doom." We switched to doing mostly Totm + owlbear rodeo for anything that needed a map and it was much easier.
