fanduel daily slot boost applied after the session instead of during it.

ran into something weird last night. got a daily slot boost on one of the big networks, but instead of it showing during spins, i only saw it added after i’d finished my whole session and went to cash out. like i played thinking it never triggered, but then my balance was way higher on exit. sort of threw off my rhythm since i usually adjust bets if boosts are working or not.

anyone else have boosts or promos show up retroactively instead of while you're actually playing? is this just how it works now or was i caught in some glitchy update?
