Regarding SSL Decryption:
I originally put the whole category of "social-networking" under a Decrypt rule (mainly to decrypt Facebook to block Facebook games). However, when I tested on my iPhone after that, LinkedIn, Twitter and Facebook all had "network errors" and basically wouldn't connect and pull down information. I then removed the "social-networking" group from the Decrypt rule, and added in a Custom group for Facebook. LinkedIn and Twitter work fine on my iPhone connectivity-wise now, and Facebook still gives a "network error" and won't update.
From what I read, TLS1.2 is not supported on the PA devices (I'm on 5.0.4), but traffic was supposed to still pass through. Why can I not still retrieve content updates on these social networking apps when SSL Decryption is turned on for them?
