I just read that storymaps will require https connections for embedded images/websites starting June 2018. Does anyone know what level of SSL certificate is required? I tried a self signed certificate for a website I wanted to embed. Chrome loaded the embedded page in my storymap with a warning, but IE11 blocked it (both cases out-of-the-box security settings). I'm wondering if I bought a simple Domain-Validated certificate, will that be enoughto get rid of the security warnings? I don't want users to have to change browser settings, or deal with any warning messages.
Thanks,
Chris
