I think there's a big difference between the ad hoc COVID online schooling and actual "doing this with planning and intent" schooling that I've seen.
It makes it hard for them to adjust fast.
The purpose built school from home programs are often far better run / budgeted IT wise. I was at my son's high school and the school from home kids were there for an in person day borrowing the lab for some in person time / activities and etc.
