A. 1. Ensure that the textures for the custom armor are correctly imported and linked in the app. Go to the armor settings and re-upload the texture files if necessary. 2. Check if the armor is compatible with the version of Minecraft you are using.

B. 1. Try creating a new armor set with different textures to see if the issue is specific to the current armor. If the new set works, the original files may be corrupted.
