@Alex27 Thanks for your response! Just to clarify, this doesn’t seem to be an issue with the sample app configuration. I’ve also tested with my own Zoom App (not just the sample), and the exact same behavior occurs.
It looks like the problem is related to the Zoom client version itself. Everything works fine on version 6.4.12, but Camera Mode fails to initiate on later versions. and I faced it on Mac, on Windows it works fine.
I also found another developer reporting the same issue here: Urgent: Production app stopped working after version 6.4.12.
