It's just a bandwidth issue - if your connection isn't good enough, unfortunately no trick will help 🤷♀️ Streaming needs decent upload speed, and if you want to watch in good quality at the same time, it gets tricky. What you can try: lower your stream quality (720p instead of 1080p, less bitrate), use the chat tab instead of another streamer's, or just have the other stream open in a background tab without actively watching it - then you need less bandwidth. In the long run, a better internet connection is really the only thing that'll help, but start by optimizing your upload settings and checking how much upload speed you actually have available.
