yeah, ToH would go like it does in Ready Player One (the book not the movie) where the protagonist downloads the module and speed runs it in minutes.
I've never had a problem with electronics at the table. But when my son's group (13 year olds) went to zoom (pandemic) and he was running rise of Tiamat, we caught one of the players literally looking at the module as my son was DMing!
I told him to frame his "don't do that!" in a "it's a lot less fun when you look at the module when we're playing..." and that seems to have worked, but who knows.
