Thank you for following up on this. To make sure that I understand, have you enabled the https://marketplace.zoom.us/docs/sdk/native-sdks/web/advanced/web-isolation feature for 1.9.5+?
If not, please try enabling that feature using the steps in our documentation. While it may not be related to the issue, you might find the following thread about using Web Isolation to be useful:
If that isn’t helpful, are you able to provide exact steps to reproduce the issue with the Sample Web App?
Finally, for anything urgent you can send an email to developersupport@zoom.us and request it is assigned to me. Including a link to this thread will help when it comes to this issue too.
Thanks,
Max
