If you walked down the street and chose the first 20 people you met and threw them on an engineering team, you'd expect the engineering product to suffer. The same applies here. We threw a whole bunch of people into working from home with no skills or experience related to WFH and, as you would reasonably expect, they are floundering.
This isn't the fault of any particular tool, rather inexperienced people not understanding how to properly use the tools they have available and conduct themselves generally. I anticipate that things will improve as experience grows, but it is still early days. A few years is still quite junior. We don't expect great software from someone who has only been programming for a few years, so we shouldn't expect great WFH ability from someone who has only been working from home for a few years.
