I added images to my message template. The images appear properly when viewed in GMail on my desktop or iPhone but they are replaces by a blue square with a question mark in it when the message is opened with the iPhone Mail program. In the settings on the iPhone Mail program: "Protect Mail Activity" is not enabled and "Block All Remote Content" is not enabled. Why don't the images display on the iPhone when opened with the iPhone Mail app? Is there a change I can make to the template that will enable the images to display properly in the iPhone Mail app? CiviCRM 5.66.0 on WordPress Version 6.5 Here is the introductory part of the HTML that references the image that appears as a question mark in a blue box when viewed with the Apple mail app on an iPhone.
