Hi @hamt!

I'm glad to hear that you're getting a little closer to diagnosing the problem.

That's a bit challenging without seeing the full code and/or logs. You're welcome to provide more snippets of either, but I understand if you don't want to publicly share them. Especially a small reproducible example of your javascript would be the most important.

Two high level questions:

1. What version of prodigy are you running? (e.g., run `prodigy stats`)
2. How are you setting up multiple annotators and/or are they annotating concurrently on the same task? Typically, there are two options for [multi-user sessions](https://prodi.gy/docs/api-web-app#multi-user-sessions): unique session ids or unique port/datasets. Here's a bit of a background on both:

> Ah, sorry if the terminology I used was confusing! What I meant was the session/instance/process. There are generally two ways you could set this up and it depends on your project, annotators and how you want to set up the workflow: Start one Prodigy process one a given host/port per annotator and save the annotations to separate datasets. For example, on port 8080, you start the Prodigy server with 100 documents and save to annotations\_andrew, on port 8081 you start Prodigy with the next 100 …

Since it's sounding like a front-end/javascript issue, I don't suspect it is a feed issue. But since you notice more issues when multiple users are annotating, I'm not ruling it out.

Feel free to add any additional things you've learned or things you think may be relevant.
