**Description**  
I’m testing instantSDK (both mobile and web versions) and I can create a session and I can join to that session using Android instantSDK and Web instantSDK. I want to be able to join to a session that is started from your production application. Is it possible?

**The requirement**  
Step by step:

1. Start a meeting with the production application ([https://play.google.com/store/apps/details?id=us.zoom.videomeetings&hl=en\_US&gl=US](https://play.google.com/store/apps/details?id=us.zoom.videomeetings&hl=en_US&gl=US))
2. Join to that session using different application that uses instantSDK
