I was looking at the go pass deluxe bonuses in game and noticed it advertised 1 guaranteed XL candy for completing 5-star and Mega raids as well as 1 additional XL candy for catching pokemon from 5 star and mega raids. This has not been working, with some 5 star raid catches only giving me 3 XL candy, even with a mega. Unless the primals purposely drop less XL this seems like a bug.
