With so many of us working from home and schooling from home, why are we getting maintenance outages during prime working hours? At the very least, we should be notified well ahead of time that there will be an outage for scheduled maintenance so we can adjust our work schedules around that.

I don't know how reliable it is, but I have sometimes seen messages about upcoming maintenance in the "My Account" app on my phone. Not sure if it showed up on the main screen or under Internet.
You can also check the Outage map, which also sometimes has a notice about upcoming maintenance:
