On my MacBook, the core feature never worked. The app requires "Entire Screen" sharing to capture audio in Google Meet, but Chrome on macOS only captures system audio when sharing a single tab, not the entire screen. So the app's requirement conflicts with a real Chrome/macOS limitation.
Support was responsive at first: I reported it, we hopped on a call, they reproduced the bug, and later emailed saying it was fixed, plus 30 credits as compensation. I retested right after. Same error.
I then requested a full refund for my subscription. That request has been ignored, no response since. They stopped answering my emails.
