I tested with the Meeting SDK Sample and I get the same error. Generate signature and join meeting with a meeting number created by not the developer account.Build SDK APP (Intend to publish: Yes) / Keep it’s not published yet.Just tested with 2.7.0 and I see the same issue.

Note: We are using role 0 to join the meeting I have been crawling through the documentation without finding any information about it, would you be able to help? Our error is that the signature is incorrect but if while testing I have Client A creating the meeting and joining its own meeting via the Web SDK it will just work. It just doesn’t work anymore with the Zoom SDK app type. You can select which microphone to record audio on, but you can. You’ll be able to set the aspect ratio and choose which camera Zoom uses to capture video. We just migrated to the new Zoom SDK app type as required to move passed the deprecation and update to the SDK version 2.7.0. Using Zoom, navigate to your profile image and select Settings from the drop-down menu. This was working exactly as expected when using the JWT app type for the Key/Secret. Client A will join the call with limited functionality but it will work. Stay connected wherever you go start or join a secure meeting with flawless video and audio, instant screen sharing, and cross-platform instant messaging.Client B doesn’t have our Zoom app installed on the account (previously JWT app and now Zoom SDK app) Client A is using the Zoom Web SDK to join.Client A is invited by Client B to a meeting.We are using the Zoom Web SDK to have our clients joining Zoom meetings.
