My personal computer is a Mac and I use the Safari web browser. I've noted a number of incompatibilities as far as displaying all links to other web pages. The most notable is on the email details page where the Social Sharing information at the bottom does not display, thus giving no visible link to the page for scheduling social media posts. (Please reference Safari screenshot attachment.) I To avoid this please test all of your pages to make sure all elements display properly in Safari as well as Chrome and IE.
