App-based Routing not working for MS Teams

Has anyone experienced app-based routing not working for MS Teams whilst OK for other application such as outlook. Match-object created includes App-Category: IM, Business-Apps, Email-Apps, VoIP-Apps, Webmail and Web-conferencing. Thank you!

Hi @ERICKSON_CHAMP,

Thank you for visiting SonicWall Community.

I checked the support case and it is progressing. I suspect the app signatures or application takes effect by blocking or allowing. If you can try blocking or allowing MS Teams via App Control and see if the signatures are taking effect? This can help us to isolate the issue.

Hi @Saravanan,

Thank you for the feedback. We have already checked and confirmed that Microsoft Teams Signatures (13903 & 13904) are set to Block: App Setting (Disabled). We have also set unrestricted app rules (action object - no action) and can confirm that the traffic is hitting the match-object. Pcap shows no drop and traffic is still traversing to VPN tunnel instead of going to X1.
