Ensure that the image URLs used in your email templates or post content are correctly formatted and accessible. Double-check that the image URLs are not restricted or blocked from being viewed on Apple devices due to any server or security configurations. Instead of using relative URLs for the images, consider using absolute URLs that include the full path to the image files on your server. This can help ensure that the images are loaded properly on all devices and platforms. Check the file formats of the images you are using in your email templates or posts. Ensure that they are in widely supported formats like JPEG or PNG, as some less common image formats may not display correctly on certain devices or email clients.
Assuming you have introduced any custom contents or modules on your site, ensure they are not clashing with one another or causing issues with the header. Incapacitate or eliminate any as of late introduced modules or scripts individually to distinguish on the off chance that any of them are causing the twofold header issue.
