Our web form is suddenly creating duplicate submissions in the database. Happens about 50% of the time. No clear pattern.
We're using Granola for frontend monitoring and have standard logging. Checked:
* No double-clicking by users (confirmed via session replay)
* No obvious JS errors in Granola
* Form endpoint is a simple POST, no redirects
Granola dashboard shows normal response times, no spikes. Need to find where the duplicate request originates. Where would you look next?
Suspect something between the browser and server. Should I be digging into network tab traces or is there a Granola feature I'm missing for tracking duplicate events?

metrics not myths
Network tab traces are a good next step. Granola's session replays show the frontend, but you'd see actual duplicate requests in the dev tools network log.
I had a weird bug once where a browser extension was replaying form submissions. Could something like that be interfering? You said it happens 50% of the time - is that for all users, or just some?
