Comcast email flipping back and forth between secure and not secure as of 10/23/19

Hi, first time here. I left a PM for Michael at Comcast and repeating my dilemma. My email keeps flipping back and forth between Locked Secure and  Circle that says not secure. Neither one show an http or https. On phone yesterday with Security in the Philippines on another issue (even tho I have encrypted PWs with Last Pass) comcast each time I would sign in told me not good PW. She said it was a Chrome problem, walked me through to do some fixes in Chrome, now that is fixed.

But now I have this flipping between the Secure and Non-secure. When I first sign in, all is good. But once I go to another secure website tab, then go back to comcast mail, it has changed back to the Non-Secure. I know CC did some email upgrades a few days ago (I received an email), so all of this started after that upgrade. And my Chrome is not the culprit. Plus when I am in the Secure and click to read my Sent mails, it changes to Non-Secure. Help please.
