Some parts of it were coupled with parents trying to homeschool their kids (for younger kids, at least, the parental attention required for remote school was high enough it wasn't too far off from simply home-schooling) while "working". Plus the extra stress of, you know, the whole being-in-a-pandemic thing. I recall some grumbling in those days about remote worker productivity and it's like, yeah, no shit, daycares and schools are all closed and households are all dual-income because game theory and zero-sum competition for housing/schools, so....

Those parts ought to be disregarded for any kind of lessons-learned from this, as far as the broader viability of WFH. 2020 through early 2021, at the very least, had some strong confounding factors going on which, one hopes, will not be common in the future.
