Bow arrow trajectory curves to the right despite aiming straight at the crosshair

In Minecraft Bedrock Edition version 1.21.81 on an iOS device running iOS 17.6.1, when I use a bow and aim directly at a target using the crosshair, the arrow does not travel in a straight line as expected. Instead, the arrow’s trajectory consistently curves to the right, even when I’m standing still and aiming straight ahead. This happens at various distances, but it’s more noticeable at longer ranges (e.g., 20-30 blocks). I’ve tested this in a single-player world with no mods or add-ons, and the issue persists. This makes it difficult to hit targets accurately, as the arrow does not follow the crosshair’s direction. The issue might be related to touch controls on mobile or a game-specific bug in this version.
