WAF blocked request from instagram app

Hi.

First, by checking the WAF console, you can check what rule was blocked.
please confirm.

Next, when you click on the link in the Instagram app as a separation, does the behavior change depending on whether it is the built-in browser or the mobile OS external browser?
If the problem only occurs in the embedded browser, it may involve some specific HTTP header such as UserAgent.

It can also be allowed by advanced settings, such as specifying conditions, adding allow rules as exceptions, and label actions for currently blocked rules to finally allow or block with compound conditions. You can.
