PS now defaults to HTTPS! This means:
1. Certain connection problems will go away.
2. PS will load faster.
3. We can use HTTPS-only features like notifications (Chrome recently made them HTTPS-only)
4. No more "Not Secure" warning.
The transition should be seamless for most browsers. Safari doesn't allow us to port teams over, though, so you might need the Team Recovery Tool. If HTTPS doesn't work for you for some other reason, we still support Insecure Mode at psim.us/insecure.
