WeChat Login Issue & File Transfer Issue

Hi All,

Trying to get WeChat to work with ZIA 2.0.
Referring to their help page, (How to Deal with Firewall Restrictions | Tencent Cloud) have added all domains mentioned in the 2 pac filec, and even the vpn gateway list.

For new login, it fails.
For existing login, file transfer fails.

I noticed it establishes connection to IP addresses directly.

e.g. 113.96.209.0/24, 113.96.202.0/24

Wondering if anyone has any luck making WeChat works with ZIA 2.0 in China.
