"For all the planning"??
Where I work, there was literally one day of planning. We were setting up equipment, lighting, microphones, and testing it all using Talent's home Internet or via bonded cellular connections one day, and going live the next. Over the following two weeks, we've been able to refine the situation through adding different technology, changing shots, adjusting lighting, etc. Has it been clunky at the beginning? Sure, but viewers seem to appreciate it, and seem to be willing to forgive the clunky start.
Can't speak for all the other Networks, but I know of nobody who had plans in advance for this.
There's always going to be some cynical A-hole that thinks they know what goes on behind the scenes, who has a forum. 99% of the time, they don't know what they're writing about.
