User's event history shows multiple sessions started at exactly the same time

Hi everyone,

I was analyzing user behavior, and in one user’s event history I found a strange pattern. On one day, the user had multiple sessions that started at the same time and ended at the same time. There are no events reported in between the Session Start and Session End events as well. Attached is a screenshot for reference.

Would appreciate any ideas on why this is happening. Right now, I suspect either the setup or user is causing this. For the setup, we initialize amplitude without setting any props at the top of our next.js app using the Browser SDK. As far as the user goes, I’m not sure what’s going on on their end. 

Thanks for reading and brainstorming with me!
