Pokémon GO confirms the following Friendship Friday bonuses are still available during the current Forever Forward season: Increased chance of Lucky Trade for any trade and two guaranteed Candy XL from trades

Pokémon GO has confirmed that the current Friendship Friday bonuses remain active throughout the Forever Forward season, giving Trainers additional incentives to trade with friends. Players continue to have an increased chance of triggering a Lucky Trade with any eligible trade, while Trainers level 31 and higher are guaranteed to receive two Candy XL from trades. These season-long bonuses make trading more rewarding by helping players collect valuable Candy XL for powering up Pokémon and improving their chances of obtaining Lucky Pokémon, which require less Stardust to strengthen. The ongoing benefits are especially useful for Trainers looking to maximize progress during the Forever Forward season.
