Arena of Valor Won’t Let Me Choose Profile Photo from Gallery

I’m unable to select a profile picture from my gallery in Arena of Valor, which is incredibly frustrating. Instead of being able to use a personal image, I'm forced to choose from the game’s awkward default photos. I’ve granted the app full permissions, yet nothing changes – I still can't select a photo from my own gallery. Arena of Valor, please fix this issue so players can customize their profiles with personal images. This lack of functionality is disappointing, and I would appreciate a prompt resolution to this problem.
