I work sales calls set up with Calendly and Otter joins them all. These are very technical so normally it's fantastic - EXCEPT if we start talking early or the prospect doesn't follow the invite and never joins the call, then they would get a transcript of my team's chatter. I learned to not allow Otter to join the call until everyone is in attendance

Whats more frustrating is that you can't disable this auto-email "feature" unless you are on a business plan of some sort. But I have a paid plan through the iPhone app and apparently can't convert it to a business plan associated with my company. So no good way to disable it

I get the network effect of referral business but sharing private conversations without consent is not the way to achieve it.
