I am reviewing and I notice that when I use the WhatsApp app and attach an image it is not sent, I do not have associated blocking policies and additionally create a real-time policy where permission is granted to upload and download files.
If I enter through a browser, if it allows me to attach all the images, I wanted to check whether netskope restricts the sending of attachments through the App?

@xavy2310 I was able to reproduce it. Apparently fat client for Windows got certificate pinned recently. You should add certificate pinning exception for Windows for process named whatsapp.exe - I have verified and it worked for me.

We have face the similar issue and found this was due to the CASB restrictions only.

Greetings, you were able to replicate. I put the exclusion as you tell me but when I attach an image it is not sent.
Hello, I can see cert pinned app is created, is it also added to Steering Exceptions?
Net result, you should see something along those lines in nsdebug log file:

The problem arises when Netskope decrypts the domain "mmg.whatsApp.net". To resolve this problem, you can include this domain in the SSL decryption exclusion rule.
Without any changes When we try in browser its working but with app its not worked.
