My guess is that the combat eats up a disproportionate amount session time.
I'm not going to tell people they're wrong here, but I have to note that PF2e combats felt a lot faster to me than D&D 3.5 ones. I mean, yeah, people could just end up fitting in more, meaning there's still a high proportion of game time taken up by combat, but that can be true in any game system that's at all combat centric (which is to say, most of them).
