The mobile Discord app has settings to turn off animated emojis and stickers, but not GIFs. Many GIFs move quickly, flicker, and have flashing lights. This cause eye strain to me which can trigger headaches, and could also affect other users who have photosensitivity. This also makes it difficult to type or respond to someone when there is a repetitive and fast motion playing on the screen. Please add the setting to turn off GIFs autoplay. Twitter has this feature, where there is a play button on the GIF, and to view the GIF you tap it to play.
