Arf, op it sounds like you had an awful experience with your dc school first time around?..
We did too, so I do sympathise that trust maybe gone.
My dc two school, one primary and one secondary really dropped the ball and let us down..
Primary didn't even give us worksheets! We were told at the beginning to collect '' work packs '' that teachers had been working hard to put together and it was an empty exercise book and a maths book. 
Dd at secondary did have work posted on line, but barley no interaction with teachers, they were terribly slow to respond to emails.. By June we had a few live sessions and it was heart breaking to see how she perked up during these.
However, my own setting was proactive, did a tech audit before lock down and proceeded to fill that gap, solve problems and make arrangements. We had a short intro to the tech and went on line within 2 days.
Pupils who did not log on were chased within minuets of registration, or their parents called. We were able to closely monitor their wellbeing, keep them learning and achieving and plugged into social contact.. Lessons were delivered pretty much the same, pupils could speak and interact and discuss.
We followed the same timetable, did the same breaks. We didn't miss a beat and yes sometimes, small snags occurred, sometimes unexpected things happened but 99% of the time it was business as usual.
Op, many other schools also managed to train teachers on the tech swiftly and get on line. Did anyone hear the head of tollworth girls school? She said they did very well on line, and students who really couldn't be helped to get on line, went into school with key workers.
She said going on line at the moment, is preferable to having burst bubbles and in and out education over the next few weeks.
So, whilst I totally understand your frustration, I do feel this time around, now it's been clear that actually, schools can get on line easily, they won't be able to get away with anything substandard again.
