In the MoM scenario "Cycle of Eternity" a Shoggoth is placed in the Study. We didn't reveal any search tokens in the Library.

When the app tells you to move the Shoggoth, is it correct that the monster can't move anywhere because of the wall placed between the Study and Library?

Rules:
Investigators and monsters cannot move through walls unless an effect specifically allows it.

Although logically it might make sense that you cannot use the door because you haven't solved the puzzle, you would need to assume that the bad guys can use it at will as the cultist does when you first enter the room.
A technicality like this shouldn't impede the monster. Just move him as if it is a door.

This is of course hoping that someone would realize that that would be a door, since it is being covered with a wall token... could be a first game and with no solid direction I can see where this would cause confusion.

Yeah, that's definitely a mistake on behalf of the coders. The app should know that there's a wall there, and thus should know not to spawn any non-phasing monster there.

In general, I'd use the following house rule: If a monster ever spawns in a room without any doors, assume there's a hidden door that lets it out if the app says it moves.
