Chrome PWA won't connect to a meeting

Hi -

I'm on a Lenovo Thinkpad C13 Yoga G1 chromebook and I just removed the Zoom Chrome app and installed the pwa. Unfortunately I can no longer start or join a meeting. I re-installed the Chrome app and all works fine as it does from other platforms. So, its not my account or network infrastructure (or even my device).

Any thoughts on diagnostics I can run or other approaches?

Thanks for any help
