Hi @YY1 - it’s hard to tell if anything is going wrong from your screenshot. The screenshot appears to show the tunnel hot-reloading your app as your code files are changed, which is the expected behaviour. Can you describe in more detail what is going wrong?
For every word or letter typed in the codes, will it reload? It returns to normal now. Thanks.
It should only reload when the file is changed on disk. Perhaps your development environment was doing some kind of auto-save?
