Not Secure Download-Links in Secure Landing Page Domain
A little while ago I added the SSL certificate to our LPs by adding the following meta tag to the <head> of our LP templates (see this post) :
<meta http-equiv="Content-Security-Policy" content="upgrade-insecure-requests" />
However I noticed, that whenever include a calender file in our E-Mails it redirects to an unsecured page/download link with the .ics file.
Shouldn't my domain have SSL, since when any "ordinary" LP is opened, it is shown as secure? What am I missing here?
Thanks in advance for any advice.
