Thank you so much for posting this because I had the same thought a few years ago but lost it π
Really good shows don't have this problem as much. There were times in Severance (my recent show obsession) where I thought some communication between characters would have made more sense - but upon reflection it seemed fair what they were keeping from each other.
But yeah some shows are like "if these two people had a 3 message text conversation the entire plot wouldn't exist" π
