Blocked UDP 443 Traffic Showing As TCP In Flows

I have a global rule to block UDP 443; All devices. I have no rules configured to block TCP 443. When I look at flows sometimes it shows the blocked as UDP 443 and sometimes as TCP 443 to the same domain. Basic stuff like youtube which is working just fine. If TCP 443 were indeed blocked that would not work. So this doesn't affect my day-to-day usage, but seems like a bug or error that should be corrected. Does make troubleshooting a bit annoying though.

  If you do not have a rule blocking TCP 443, then it is likely a display bug. I've created a ticket for you, so we can follow up.
