Presence.update loop works once then returns {:error, :nopresence}

I’ve been doing some digging today and think I discovered what may be causing the problem.

I’ve included a ton of IO.puts so you can see what’s happening.

When I inspect the metas before the update that succeeds, notice it has both phx_ref and phx_ref_prev metas. But on the one that fails, it doesn’t have the phx_ref_prev meta.

I’ve confirmed this pattern happens for every update that fails, even if that update runs first in the loop.

I don’t have the right answer yet but am getting closer and will update you all when I figure it out. I’m assuming there’s an issue with my update_presence function that compiles the metas.
