It definitely doesn't help that, as the user Sol Pacificus has mentioned, Ubisoft in general seems to have forgotten that the game exists. It's not on their website and is no longer available on iOS. The only times it's been referenced is the brief suggestion in Brotherhood's Pidgeon missions as well as a brief reference in the database entry for the North Atlantic in Rogue.

The database entry mentions that Abstergo insists on spelling Columbus' name as "Christoffa Corombo", with Violet stating that she doesn't know why aside from it having something to do with Desmond. It's a reference to the fact that that's what Columbus was called throughout the events of Discovery.

Anyway, given all of that, it wouldn't at all surprise me if Aymar only has a vague recollection of Discovery's plot and, as such, wasn't fully informed when he stated that it was no longer canon.
