Interesting! I would think it would silently fail by trying to sign an event with a differently populated public key, but if you’re saying it doesn’t do that, I would indeed say it’s a problem.

I had two safari tabs open. One on Iris, one on Coracle. And each one had a different pub key signed in.
I was on Coracle and writing a post, but Nostore setting was set to the profile that was logged in on the other Iris tab.
When I hit post, it jumped me to Iris and posted there 😂
