HI David,
So here the issue is : intermittent incoming presentation on SX20 during WebEx calls, after relocation.
It seems to be a network / firewall issue .
Please have a look at the following link to make sure all ports and IP address are opened to Allow WebEx Traffic in your network :

I have similar issue on DX80 and SparkBoard that is registered to Spark. We use PA firewall as well.
If we disconnect the call while the content is shared, and rejoin, then content shows up.
Has anyone found if the problem is Firewall related?

Hey Charles - Did you ever find a solution for this issue? We're having the exact problem. Using mostly MX800's and our Network Engineer doesn't see any blocks at the Palo Alto firewall.
Thanks

We worked with Cisco and Palo Alto support. Turns out we were hitting the default Palo Alto UDP timeout of 30 sec, which was causing the issue when the sharing started > 30 secs after the video endpoint joined the meeting. They had us create a separate firewall Application rule where we increased the timeout to 10800 sec, which resolved the issue.

David, We have the same issue with RoomKit on content sharing with Palo Alto firewall. Can you provide me both the Cisco and PAN ticket, so I can call them to refer to? or if possible what exactly you have to do on the PAN to make it work?
