AI Companion doesn't consistently generate meeting summary

Hi, I'm probably having a 50% success rate with AI companion actually generating a meeting summary. I get this message:  I apologize, we are unable to generate what you need because the input provided does not contain sufficient information. Please check whether the input is too brief or unclear.

Meetings are 30 minutes. Very clear action items in the meeting. Typically these meetings are me and one other person. All my settings are set properly (cloud recordings, generate meeting summary, ai companion on from the start, etc.). Any idea what's going on? My next step is to get a different AI notetaker but would rather not pay for another tool.
