I see, thank you for the feedback. According to the GitHub issue provided by @Scroogey however you use by default the "slow" mode if you use Robosats on your phone (unless it changed since May 2024). Indeed in the GitHub issue it says: "The Android app uses the HTTP API of the chatroom. On browser, we use Websockets for instant messaging, but the HTTP API is also available (under the name "Turtle mode" the small icon between the two chat status indicators)."

But I am like you, in "slow" mode it works just fine for me as well.
