I noticed that after the V0 upgrade, which seems to be an upgrade to Next.js 15, the preview page speed has decreased, and the responsiveness is very slow!
I believe that regardless of any upgrade, responsiveness and speed must remain the absolute top priority. This is the core of the user experience. The current degradation means my preview efficiency is significantly lower, and I can only imagine how much my productivity will drop over time
