Hello there, DevlinR Maguire.
I've checked for similar reported issues in our list and didn't find any. They can perform a few browser troubleshooting steps to clear stored files. Piled-up cache files can cause regularly visited sites not to function well.
- Let them open their emails through a private browser and check the emails from there. This is to see if the contents are shown well.
- If it worked fine, let’s clear your regular browser’s cache to remove those files that were stored.
- Other browsers can help us get rid of this unusual behavior. We support Google Chrome, Internet Explorer, Mozilla Firefox, and Safari browsers.
Keep me posted on how this works.
