You managed, good for you! Thankfully, we got it better, and kids these days have it even better. I don't see how that's a bad thing, every generation should strive to make things better for the next ones.
I don't think it's "better" to make kids check a multitude of ever-changing apps and screens just to find out their timetable for the day.
What on earth is the point? When I was a kid we just had the same timetable repeating every week. It changed once a year, at the beginning of the academic year, meaning that within a few weeks I knew it from memory and didn't need to keep looking it up.
In the extremely rare event that things deviated from the timetable, the school found a way to tell us. It's not hard to convey a message to a group of students when you know exactly which room they'll physically be in at any given moment; another advantage of a fixed timetable.
If the school can't accomplish such basic tasks as scheduling a simple timetable, that's the adults' problem, not the children's.
