THANK YOU for posting this. My partner uses Otter, and HIS Otter bot will join my work meetings that he is not even invited to. He's sent me some recordings within the app in the past and we share calendars, but it still doesn't explain why this would happen. We've emailed Otter multiple times since July 2021 without any satisfactory response or investigation. You'd think they would take this privacy issue more seriously. Truly absurd.
