Default data center region selection behaviour prior to the recent Video SDK JWT changes?

I was going through the changelog for Video SDK for Android which was posted on 29th June, 2022. It says:

New optional field in JWT payload to allow setting the data center region preference for the session. Specify the data center location used by the participant, separated by commas.

Valid geo regions:


Does anyone what the default behaviour was before introducing this? How were the data centers selected? Also, what’s the behaviour when it’s not specified since it’s optional?


Good question! @vic.yang any thoughts on this please?
