On switch, the ZL trigger no longer does anything in negotiations or battles. In a negotiation, there is no ZL on the bottom bar where all of the other commands are noted. This means there is no way to examine arguments or intents during negotiations, or to examine fighters and their statuses during battles. Also, ZR still works to examine an individual during conversations, but it is not possible to scroll though their description and read past the top of the page, or examine their loot cards.
Start a Rook game on Switch, prestige 2, normal mode. ZL should be missing from negotiations and battles.
