Hi @Bob_K,
Unfortunately this happens for many apps on macOS as these apps disabled virtual cameras at all.
What can you do:
- Try to download older version of your app (please share the link here).
- Some users suggested this workaround, but I don’t recommend it from security point of view: ManyCam virtual Cam with Zoom 4.6.9
- Contact Amazom Chime support and request a fix
- Submit a feedback to Apple so they provide a solution for virtual cameras to work: https://www.apple.com/feedback/macos.html
