Ok. Let me know if the issue persists. It is also possible that it was a spam prevention measure from your email provider or mail client as emails containing multiple links can be flagged as spam.

Generally, all links from other senders come in hyperlink format in my email client. I believe that until recently, all of your links sent via email were hyperlinks, especially with the charts themselves.

That might have to do with a setting in your email client. The email was sent out as HTML, which means that the hyperlinks are clickable, but some email clients (Outlook, Thunderbird, you phone, etc.) may be set to receive emails in plain text format, or at least from senders that are not on your trusted list.
When new posts with a video or charts are sent out, you can only view the video screenshot or chart images if the email comes through as HTML. Do you recall if you usually can view the charts & clicks on the links? Has anyone else had the issue where the links were not clickable?
