I updated from 5675 and after that I noticed that messages via sendEndpointMessage are sent twice.
window.APP.conference.sendEndpointMessage("",1321231) via dev console
console.log(action) to line 54 in
/react/features/subtitles/middleware.js (or any other middleware which handles endpoint messages
As you can see, the sendEndpointMessage with 1321231 as payload is received 2 times on the right side. The other endpoint messages are from “e2e-ping-request”.
Happens with Chrome and Firefox.
This is what I get with the old version
