I completed the Levantine Brotherhood community challenge but don't appear to have received the reward. It says it's claimed, but I had no icon pop up on screen to say I received the reward as I usually would and there is no tattoo sitting in my inventory.
I saved and closed the game before reloading and it still didn't appear. As I'm questing in the world, I haven't been able to visit my settlement to check if the tattoo has just appeared, but since that's not the way it usually works, I'd be surprised if that was the answer.
I haven't seen any other complaints online about this, so assume it's not a common issue. I play on PS5.
