Thanks @c10b10! Just to clarify, does the issue only happen with the `subscriptions-transport-ws` subprotocol? If that's the case and you need to fork the server too, you can find that...

Hi @c10b10 👋 Your reproduction was _very_ helpful, thanks! An important element in reproducing this bug is related to your specific WebSocket API (and explains why we don't see it...

@c10b10 I've confirmed this is a timing issue with React 18's automatic batching: wrapping `useSubscription`'s `setResult` in [`flushSync`](https://react.dev/reference/react-dom/flushSync#flushing-updates-for-third-party-integrations) produces the "old" behavior by forcing a re-render for each message, even...

Hi all 👋 I've created an RFC (https://github.com/apollographql/apollo-client/issues/11705) for the schema-driven testing work I described above. I'm going to close this issue out, since that RFC is a better place...

Hi all 👋 Both the devtools and `@apollo/client` have put out recent releases with various improvements to the registration mechanism that should resolve this issue. Please ensure you are running...
